What is an infrared imager
Infrared imager is a device that uses infrared radiation to detect and image. It is widely used in military, industrial, medical, security and other fields. It helps users observe and analyze in dark or low-visibility environments by capturing infrared radiation emitted by objects and converting it into visual images. This article will introduce in detail the principles, application scenarios and popular products currently on the market of infrared imagers.
1. Working principle of infrared imager
The core principle of infrared imagers is based on the infrared radiation emitted by objects. All objects with a temperature above absolute zero (-273.15°C) emit infrared radiation, which typically ranges in wavelength from 0.75 microns to 1000 microns. Infrared imagers capture these radiations through sensors and convert them into electrical signals, ultimately producing a thermal image.
