What is infrared detector used for | infrared detector
Infrared detectors are passive detectors that do not emit electromagnetic waves themselves, so they can detect the enemy without exposing themselves. Provides the possibility to covertly find the enemy. It can provide a blurred image of the enemy.
The basic principle of an infrared detector is a device that converts the incident infrared radiation signal into an electrical signal output. Infrared radiation is electromagnetic waves with wavelengths between visible light and microwaves that are imperceptible to the human eye.
Infrared detectors work by detecting infrared rays emitted by the human body. The detector collects the infrared radiation from the outside world and concentrates it on the infrared sensor. Infrared sensors usually use pyroelectric elements, which will release charges when receiving infrared radiation temperature changes, and generate an alarm after detection and processing.
This detector is aimed at detecting human radiation. Therefore, the radiation-sensitive element must be very sensitive to infrared radiation with a wavelength of about 10 μm. | infrared detector
