To understand the principles of night vision, it is necessary to know something about the principles of light. The amount of energy in a light wave is related to its wavelength: the shorter the wavelength, the higher the energy. In visible light, violet light has the highest energy, while red light…

Both plants, animals, humans, cars and objects emit heat. The defining characteristic of a thermal sensor is the detection of heat in response to small differences between thermal features in the image. So whether it's raining, sunny or completely dark, thermal imaging cameras provide clear thermal…
