UNCOOLED IR DETECTOR ARRAY HAVING IMPROVED TEMPERATURE STABILITY AND REDUCED FIXED PATTERN NOISE

摘要

An infrared radiation detector array for providing an image signal of a scene is provided including a plurality of infrared radiation detectors having infrared radiation responsive elements. Each one of the plurality of infrared radiation detectors provides a proportionate electrical signal in response to infrared radiation of the scene incident thereto. At least one blind infrared radiation detector having a radiation responsive element is provided and shielded from infrared radiation of the scene. The blind infrared radiation detector provides a proportionate electrical signal in response to infrared radiation incident thereto. The blind infrared radiation detector is configured to provide a signal indicating thermal distortion of the infrared radiation detector array.
