Infrared Helicopter Uncovers ‘Fight Club’

In the middle of the night, at a closed Winn Dixie parking lot in Orlando, Florida, a ‘fight club’ assembled and began voluntarily assaulting each other. The Winn Dixie employees had gone home and no shoppers were in sight. Two men, an 18-year-old and a 21-year-old, were caught engaged in their illegal activities by a thermal imaging camera mounted to a police helicopter while it floated quietly above. (See video above.)

The helicopter called local patrol cars below to intervene. The suspects ran, of which the 18-year-old ran into the woods to evade both the helicopter and the police on foot, but thermal imaging spotted him through the trees from above. The police helicopter coordinated with law enforcement on the ground, and all suspects were caught. Both men now face charges of public fighting and resisting arrest.

First Aerial Infrared Footage of L.A. Natural Gas Leak

Thousands of residents from upscale community Porter Ranch, California, as suburb of Los Angeles, have been relocated after becoming sickened by nearby massive gas leak that began in October 2015. The natural gas well was originally an oil field but was quickly depleted over a 60 plus year span. In the 1970s, the land’s owners pumped in natural gas into the empty well to be stored and later used when prices were higher. As nearby residents began experiencing nausea, nosebleeds, dizziness, and headaches the utility provider SoCalGas allegedly informed local authorities 3 days after detection according to court documents. The residents were initially told they were feeling sick from the rotten-egg smell added to the natural gas which is used to alert customers when they have a gas leak in their home as natural gas is odorless, but it was further revealed that compounds that can cause cancer, for example benzene, were elevated beyond their legal limits. Residents and media took to using infrared cameras to show the dramatic effect of the gas leak, as well as to provide peace of mind when it is resolved. By adding a special filter and using a specific bandwidth of the infrared spectrum, infrared cameras can detect gases including natural gas in the atmosphere to be shown in the visible spectrum. The above video was taken with a special infrared camera from a helicopter showing what is invisible to the naked eye or traditional cameras. SoCalGas has been working on building a new relief well adjacent to the broken well to siphon the gas to a new receptacle, after which time the old well will be filled with mud and sealed with cement. The leak was stopped last week, but the families won’t start moving back to nearby homes until state authorities have certified that cement pumped into the well has permanently plugged it.

Update: On February 17, SoCalGas pleaded not guilty to misdemeanor charges stemming from the ruptured well in California that leaked for weeks. The complaint brought by the county district attorney includes three counts of failing to report the release of a hazardous material and one count of discharge of air contaminants. If convicted, the company could be fined up to $1,000 per day for air pollution violations and up to $25,000 for each of the three days it didn’t notify the state office of emergency services of the leak.

Christmas Shown From Space Using Infrared Process

Nasa Photo of Christmas Lights

New photos created from NASA’s Suomi NPP satellite, shows the extent of holiday light displays in the U.S. compared to the rest of the year. By comparing the light from the Christmas holiday with the rest of the year, the differential is extracted and shown on the map. Scientists found that nighttime lights around major U.S. cities shone 20 percent to 50 percent brighter around Christmas. Dark green in the key is used to indicate areas where lights have the largest gain mostly suburbs being 50 percent brighter in December. The images released were taken between 2012 and 2013 and include 70 American cities. The difference is most pronounced in suburbs and small towns where residents have bigger yards and bigger homes. Lights were brightest between Thanksgiving and New Year’s Day.

The Suomi NPP weather satellite, launched in 2011, has a sounder infrared spectrometer named Cross-track Infrared Sounder (CrIS), and a scanning radiometer named Visible Infrared Imaging Radiometer Suite (VIIRS). Since 1980, polar-orbiting weather satellites have included both imagers and sounders. These types of sensors record data continuously, using different wavelengths to infer information on a global scale.

The CrIS sounder infrared spectrometer is an instrument measuring temperature and water vapor as a function of different heights within the atmosphere. The scanner collects multiple spectral data via 1,305 separated spectral channels (sensors), internally separating infrared energy into wavelengths, similar to a weather balloon. CrIS produces high-resolution, three-dimensional temperature, pressure, and moisture profiles. These profiles are used to enhance weather forecasting models, and they will facilitate both short- and long-term weather forecasting.

The VIIRS uses radiometric and infrared imaging, thereby using a color pallet to ‘paint’ polarized heat images by assigning color to each heat temperature, which is the sole instrument used to create the above map. VIIRS collects visible and infrared imagery and radiometric measurements of the land, atmosphere, cryosphere, and oceans. VIIRS data is used to measure cloud and aerosol properties, ocean color, sea and land surface temperature, ice motion and temperature, fires, and Earth’s albedo. VIIRS can record infrared light even in the presence of clouds, moonlight and air particles.

Together VIIRS and CrIS combine infrared instruments and can determine cloud top height and thermodynamic phase (ice or water particles), and make estimates of microphysical and optical properties that indicate the amount of water and ice in the cloud layer. The Suomi NPP satellite is the result of a partnership between NASA, the National Oceanic and Atmospheric Administration, and the Department of Defense.

Thermal Imaging Facial Recognition System In Works

GroupofGuys

The problem with current facial recognition systems using optical CCTV cameras is that when it’s dark the analytics can’t make heads or tails what’s going on. Thermal infrared would solve this problem but with it’s current limitations it can’t see the kind of facial details that traditional lighting highlights in a person’s face. A group of German scientists claim to have found a solution to this issue, limiting infrared cameras, by creating a new system that analyzes a person’s thermal signature. To accomplished this, the scientists first gained access to a previous study’s archived database of optical and thermal infrared photo profiles created for 82 individuals. Second, the scientists fed 41 of these complete profiles, or half, into a deep neural network computer system, so called due to it’s ability to use artificial intelligence to ‘learn’, and taught the computer to compare a person’s thermal infrared profile with their optical photo. The computer’s analytics was put to the test to see if it was able to make accurate identification by feeding the remaining 41 profile photos at random into the computer. Amazingly, it was accurate by 10% greater than the latest state-of-the-art traditional optical CCTV methods of facial recognition. But there is still a long way to go before it is put into real life situations due to the fact each person’s study profiles on average had 55 photos, thermal and non-thermal.  The computer’s facial recognition accuracy reaches only about 80% when there are a few optical images in its database to compare to the thermal image. With only one optical image available per person, the accuracy of the system falls to 55%.

Thermal Camera Observes Computer Hack Using Heat

Highly secure computer systems, referred to as “air-gapped systems”, are not connected to the internet or connected to other systems connected to the internet so their data can’t be hacked and stolen. These systems are used in military complexes, payment systems, or systems that control critical infrastructure, to name a few examples. But investigators have found a new way to hack into these systems — using heat. Researchers are also using thermal infrared cameras to observe the process (see above video). By having an infected computer that is connected to internet placed near the non-internet connected computer, for example, a laptop that goes home with a worker and returns to the office placing it near the air-gapped classified system, the internet hacker manipulates the laptop’s temperature in a pattern creating 0’s and 1’s communicating to the air-gapped system via it’s thermal sensor that is normally used for its cooling fan. At present time, the rate of information exchanged via heat signals back and forth is slow but information such as password transmission has been demonstrated. Researchers are determining if internet connected air conditioning systems can also communicate with these offline classified computers sometime in the future as this method develops.

Police Gear Up To Watch Beaches With Thermal Imaging

As police departments become more militarized, Miami Beach’s officers will be prepared for Memorial Day weekend, locally known as ‘Urban Beach Week’, on a whole new level. Their equipment includes: multiple mobile cameras, 3 watchtowers, 62 light towers, 12 messaging boards, 18 stationary CCTV cameras (monitored throughout the city), multiple license plate readers (on the causeways to quickly scan for stolen vehicles or owners with outstanding felony warrants), 400 officers on duty around the clock, and ATV’s. What’s of interest to this blog is that they will have an all new light tactical all-terrain vehicle or “LTV”, which is a $140,000 vehicle similar to the ones used in the military. This highly advanced vehicle has a built in thermal imaging camera to patrol and detect heat signatures on the beach. Even in the dead of night, with zero light conditions, officers can see people on a small screen mounted inside the vehicle, detecting people as far as 3/4 of a mile away who are trespassing on the beach after hours, or other criminal activity. Officers liken a dark beach in Miami to a dark alley in New York City.

Humans Can See Infrared Light Thought Impossible

Lumistar - Blog - Infrared Vision

Researchers at Washington University in St. Louis, Missouri, were able to get subjects to see in the infrared with the naked eye. Researchers used infrared laser beams (pure focused infrared beams) at different wavelengths to conduct their experiments. The key to their safety in these experiments and ultimately it’s usefulness in medicine was using a less powerful infrared laser beam, not one that can damage the retina like conventional laser pointers used in lecture halls or as toys.

There were reports in the past of humans could see infrared light in scientific literature during experiments, but they were unexplained and thus the myth remained human retinas were incapable of seeing ‘invisible’ infrared. For researchers at Washington U. to conduct their experiments, laser pulses of different duration were delivered with the same number of photons, defined as the particles that make up light whether visible or invisible like infrared. Their findings: if the infrared laser pulse was short enough to ‘stack’ the photons picked up by the photoreceptors in the retina, two photons hitting the retina instead of one, it caused the invisible wavelength to mimic a visible wavelength half it’s strength, becoming a wavelength visible to the naked eye. The key is to get the beam in the visible spectrum or the ‘rainbow’ which is in the 400-700 nanometer range. At near infrared (NIR) 1,000 nanometer wavelength, with two photon hits, it became a 500 nanometer photon thus in the visible wavelength range. By making the pulses short in order to bombard the retina the subjects didn’t see ‘pulses’ but instead saw a duration of light. In standard vision, only one photon is absorbed at a time by your photoreceptors on the back of the retina, which then create a molecule called a photpigment read by the nerves leading to the brain creating vision.  The benefit to all this is whereas using visible-wavelength lasers might damage the retina in potential medical treatments, this technology will develop new tools to examine the healthy eye by stimulating specific parts of the retina to see if it is properly functioning. By doing so doctors can learn more about our eye’s structure and function not only in healthy eyes but in people with retinal diseases such as macular degeneration.

In case you were wondering, all 30 volunteers described infrared as very short pulses of pale green light and longer pulses of reddish light.

After studying Emperor penguins using thermal imaging cameras, scientists from Glasgow University in Glasgow, UK discovered that these Antarctic birds keep warm by an unusual phenomena where temperatures can reach -40C. Studying penguins In the French-claimed sector of Antarctica named Adélie Land, scientists  discovered that penguin’s feathers or plumage are colder than that of the surrounding air. As a result thermal radiation, heat from the warm bodies is lost to the colder air, is minimized. Penguins, similar to humans at 37C, maintain core temperature of approximately 36.9C but only their eyes, beaks, and feet were warmer than the surrounding air, and only their eyes are above freezing. Similar to fighting fire with fire, Emperor penguins fight cold with cold. Thermal Imaging confirmed that penguins coats are four degrees Celsius colder than surrounding air. Penguins are able to accomplish this by having their coats face the upper atmosphere which is 20C colder than the surrounding air. For example, according to Glasgow scientists, a similar phenomenon can be observed if you park your car in the open on a cold night. Usually you will only find frost to have formed on the roof and windscreen but the sides do not ‘view’ the sky and therefore are radiating to relatively warmer surroundings. Penguins plumage is also so insulated it is equivalent to humans wearing two ski suits. Computer simulations confirmed their findings.

Physicists Harvest Infrared Light Into Energy

Lumistar-Blog-Infrared Earth

Possibly as a future add-on to solar panels for harvesting energy at night, physicists at Harvard University have found a way to capture thermal infrared energy that escapes every night into space by the very act of allowing it to escape.  By using the principal of hot and cold differential to harness electrons into voltaic current, similar to how radioisotope thermoelectric nuclear batteries are used on artificial satellites, the thermal power generator would capture the infrared photonic energy with the use of a “hot” plate, as warm as the Earth, with a “cold” plate on top made from a material that would quickly radiate the thermal infrared electromagnetic photonic wavelengths back to the cold vacuum of space.  During a pilot study in Lamont, Oklahoma, the researchers have calculated that the heat difference between the plates could generate a few watts per square meter, day and night. This natural radiation happens every night with some of the infrared energy being trapped by our atmosphere to keep the planet from being as cold as space, thus named the greenhouse effect. With the sun bombarding the Earth with infrared heat that escapes every day and night continuously back to space this is clean energy that can eventually be used. Scientists hope to create a working model and become further efficient producing additional watts by using nanotechnology making efficiency possible.
