Abstract
An infrared imaging system having functionality for maintaining image quality in the presence of temperature drift of the system. Such functionality is applied repetitively to maintain image quality of a target scene, yet without continuous actuation of a shutter of the system. The functionality of the imaging system results from implementing an imager algorithm. In use, the imager algorithm functions with a calibration curve created for the imaging system, with the curve comprising a plot of system output versus target scene temperature.
