What Is an Infrared Imager?
An infrared imager is a specialized device designed to detect and visualize infrared light, which falls outside the visible spectrum and is imperceptible to the naked eye.
Unlike conventional cameras that capture images based on visible light, infrared imagers can see in total darkness or through adverse weather conditions by detecting infrared radiation. This technology finds wide application in fields such as surveillance and security, particularly in environments with low light levels, as well as in building inspections, medical diagnostics, and numerous other areas requiring the ability to see beyond the capabilities of human vision.
The core technology behind an infrared imager involves detecting infrared radiation, translating it into electrical signals, and subsequently converting these signals into visible images. This process is facilitated by using thermal sensors and semiconductor devices, which are sensitive to temperature variations and infrared light absorption, allowing for the accurate rendition of an infrared scene in visual form.
