Abstract
This chapter deals with the historical evolution of infrared technology from the first prototype developed in 1958 to the multitude of models, which are available today. Particular attention is devoted to the detectors’ working principles, their characteristics and performance as well their main fields of application. A section is devoted to radiometric systems involving: image generation and uniformity correction.
Keywords: Infrared device, historical evolution of infrared devices, performance of infrared cameras, IR image generation, cooling systems of IR detectors, IR detector materials, uncooled detectors, radiometric systems
