How Do Forward Looking Infrared Radiometers (FLIR) Systems Function?

22/6/2016

In the 1970s, the US military developed a technology they termed ‘FLIR’. This technology enabled these professionals to create images through fog, dust and various other obstructions that hindered or reduced visibility levels. FLIR devices typically use heat for creating these images. Many people tend to confuse FLIR with night vision. However, night vision cannot operate in conditions that have zero visibility levels.

Aircrafts and satellites typically rely on thermal imaging systems as well. However, these systems will usually look sideways i.e. peripheral to the direction in which the plane or satellite is travelling. In contrast, the FLIR device will always look in the direction in which the device is moving. This is because FLIR devices often act as a set of artificial eyes for helping humans view things that would otherwise be invisible or obscure.

FLIR systems will feature infrared technology that enables the device to sense the differences in the levels of heat in a specific area. Based on this, it will yield images that highlight these differences in temperature on the monitor. This capability makes FLIR systems invaluable. Because these devices operate on the principle of detecting heat, they do not require light for functioning. As such, they can yield images even in conditions of zero visibility.

What Kinds of Thermal Image Cameras Are Available for Purchase Nowadays?

cameras will exist as well. People typically distinguish infrared cameras into two types. These comprise:

Cameras with Cooled Infrared Detectors: Cooled detectors typically lie in vacuum-sealed cases and cooled cryogenically. Cooling these detectors is essential for the smooth functioning of the semiconductor materials used in the camera. Without cooling, the sensors in these cameras would remain blinded by the radiation the device itself emits.
Cameras with Uncooled Infrared Detectors: These drone thermal cameras use sensors that operate at ambient temperatures. Or, they could use sensors stabilised at temperatures close to ambient temperatures with the help of small temperature control elements. Some detectors operate by measuring changes in the resistance, voltage or current, when heated by infrared radiation. The devices then compare these changes with the values at the operating temperature of the sensor. Because these do not require cooling to low temperatures, they do not require bulky or expensive cryogenic coolers. This is why these cameras will be smaller and relatively inexpensive.
Miscellaneous: Other types of infrared cameras include:

Short Wavelength Infrared Cameras: Defined by water absorption, these are ideal for long distance telecommunication
Mid Wavelength Infrared Cameras: These come into use in heat-seeking missile guidance systems. They are popular in infrared camera systems used for thermography as well.
Long Wavelength Infrared Cameras: These require zero light for operating, because they measure only heat emissions. These cameras come into use in law enforcement, surveillance, security, search and rescue, medical and veterinary thermography.

How Do Infrared Cameras Actually Work?

The human eye can only see a portion of light in the entire electromagnetic spectrum. This is visible light. The light that remains invisible to the naked eye include X-rays, gamma rays, infrared rays, ultraviolet rays, microwaves and radio waves. In the electromagnetic spectrum, light exists in frequencies or wavelengths. And, infrared light occupies the frequencies between microwaves and visible light.

Each object contains molecules and atoms, which are always in motion. This motion results in the creation of heat, which in turn, means that each object radiates heat. At the level of heat increases, the number of molecules and atoms that move and create increased levels of infrared rays will increase as well.

Infrared cameras typically feature specially designed lenses. These lenses are able to convert heat into an electronic signal. Thereafter, the camera displays this electronic signal on a monitor. Because infrared cameras can detect heat, they usually feature the ability to calculate the heat that an object is radiating. The images that infrared cameras yield can reveal the differences in temperature levels. Because of this, many people use it for determining the lack of insulation or to plug leaks in walls. This is useful for making properties energy efficient. In addition, some technicians use these cameras for determining overloaded circuits as well
