The same technology as conventional cameras is used in night vision equipment, but at a higher magnification. These devices check for visible light in nighttime conditions and absorb it. This light is then multiplied and shown in visuals with a greenish tint. “Image intensifier” devices are also known as night vision devices
This is a better, more particular descriptor for them, because “night vision devices” encompasses both image intensifiers and thermal imaging or infrared cameras, as they all help in night vision. PVS-14 Night vision image intensifiers are a simple technology that works in the same way as a regular camera but amplifies any light available. The main disadvantage of night vision image intensifiers is that their efficacy reduces as the amount of nearby light decreases.
Why do night vision goggles look green in color?
The photons that contact the front lens of night vision goggles convey light of all hues, even at night. However, there is no way to save that information when they are transformed to electrons. Because human eyes are more sensitive to green light, the phosphors on their displays are purposefully selected to produce green images. It’s also simpler to stare at green screens for lengthy periods of time than it is to stare at black and white panels (which is why early computer screens were mostly green). As a result, night vision goggles have an unsettling green light to them.
What are the applications of thermal imaging
Thermal imaging, often known as infrared imaging, is a technique that uses infrared scanners to compare the heat signatures of things to those of other items nearby, and then converts those heat signatures into a picture with the higher heat signatures highlighted brighter and easier to view. This technique has several uses in a variety of contexts, but not everyone is aware of its breadth of utility.
Uses of thermal imaging
Aiding nighttime drivers: The infrared camera provides excellent visibility in low-light circumstances, making it perfect for nighttime driving. This is especially true for persons who live in rural, hilly, or forest environments with a lot of animals.
High-dollar vehicle owners
Luxury automobiles, RVs, corporate cars, and high-end trucks that transport expensive assets such as boats or other goods must be protected from any possible dangers. These are significant assets, and everything that can be done to keep them secure, particularly at the most hazardous time of day to travel (at night), is just prudent asset protection.
Military and law enforcements application
Military and police groups do utilize PVS-14 infrared cameras not just for driving but also for recognizing persons in low-visibility circumstances, detecting concealed weapons on suspects, and tracking in chases.
Hunters
Hunters can use infrared cameras to track where prey is most abundant in stakeouts and to view unsuspected animals in dense bush, lakes, or woods when out hunting, especially at night.
Firefighting
An infrared camera can quickly detect a fire, pinpoint the hotspots, and show doors that are dangerous to open due to fires on the other side. These cameras are ideal for this situation because they can see through thick layers of smoke that may be present around the fire.
