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