Abstract

While uncooled microbolometer cameras have made infrared imaging accessible to a much wider range of applications than their cryo-cooled competitors, they are notorious for having poor noise performance and problems with calibration drift. The drift causes microbolometer cameras to lose radiometric accuracy over time, and this is a serious problem for radiometrically combining multiple detector arrays because the drift is not the same for each camera, and existing calibration methods cannot adequately compensate for it. We show methods to dynamically correct for calibration drift during measurements, so that multiple detector arrays can be kept in radiometric agreement with one another.
