1, the application of different
Infrared thermal imaging technology in both military and civilian applications, the beginning of the origin of the military, and gradually turned to civilian use.
Infrared night vision is the use of photoelectric conversion technology of the military night vision instrumentation.
2, the role of different
In civilian use is generally called thermal imaging camera, mainly used in research and development or industrial testing and equipment maintenance, fire prevention, night vision, as well as security are also widely used. In layman's terms, a thermal imaging camera transforms the invisible infrared energy emitted by an object into a visible thermal image. The different colors on the top of the thermal image represent the different temperatures of the object being measured.
Night vision instrument to image intensifier as the core device of the night outside the sights, its work does not use infrared searchlight illumination of the target, and the use of weak illumination of the target reflected light through the image intensifier in the fluorescent screen enhancement for the human eye can be felt as a visible image to observe and aim at the target.
3, different working principles
Infrared thermal imaging camera is a use of infrared thermal imaging technology, infrared radiation detection of the subject, and signal processing, photoelectric conversion and other means of the subject of the temperature distribution of the image into a visual image of the equipment. An infrared camera accurately quantifies the actual heat detected and images the subject matter in real time in the form of a surface, so it can accurately identify suspected fault areas that are heating up.
The phased array on the infrared detector element scans the converging light. The detector element generates a very detailed temperature pattern called a thermogram.
