Infrared Imaging — Telvision in the Dark

Television cameras convert reflected visible light into electrical signals, processes them, and displays the image on a video monitor. Infrared (IR) cameras collect long wavelength radiated light and convert it into electrical signals that can be displayed on a remote TV screen. Infrared cameras, therefore, do not require any source of light to produce an image because the subject itself is the light. — This article is intended to be an introduction to infrared video and the electromagnetic spectrum it occupies. Also discussed is basic IR concepts, a history of IR technology, the future of IR imaging, applications of IR imaging to television, and other commercial uses.
