The difference between thermal imager and night vision device
Infrared thermal imaging technology has applications in both military and civilian areas. It originated from military use and gradually turned to civilian use. It is generally called a thermal imager in civilian use, and it is mainly used in research and development or industrial inspection and equipment maintenance, and is also widely used in fire prevention, night vision and security. In layman's terms, a thermal imager converts the invisible infrared energy emitted by an object into a visible thermal image. Different colors on the top of the thermal image represent different temperatures of the measured object.
The night-time external sight with the image intensifier as the core device does not use infrared searchlights to illuminate the target when it works, but uses the light reflected by the target under weak light to be enhanced into a visible image that the human eye can perceive on the fluorescent screen through the image intensifier to observe and aim. Target. Infrared night vision device is a military night vision device using photoelectric conversion technology. It is divided into two types: active and passive: the former uses infrared searchlights to irradiate the target, and receives reflected infrared radiation to form an image; the latter does not emit infrared rays, but relies on the target's own infrared radiation to form a "thermal image", so it is also called "thermal image". instrument".
