What is a thermal scanner?

Thermal scanner is to use infrared detector, optical imaging objective lens and photo-mechanical scanning system to receive the infrared radiation energy distribution pattern of the measured target and reflect it on the photosensitive element of the infrared detector. Between the optical system and the infrared detector, there is a photo-mechanical scanning The mechanism (the focal plane thermal imager does not have this mechanism) scans the infrared thermal image of the measured object and focuses it on the unit or spectroscopic detector. The detector converts the infrared radiant energy into electrical signals, which are amplified, converted or The standard video signal displays the infrared thermal image through the TV screen or monitor.
