Abstract
A simple digital recursion relation has been developed to restore images which have been degraded by the AC coupling characteristics of infrared imaging sensors. The recursion relation is derived and shown to be equivalent to inverse filtering. To indicate the magnitude of the distortion due to AC coupling the RMS deviation between input and output signals is calculated for a single rectangular pulse and a series of rectangular pulses. Examples of images before and after the recursive restoration process are shown.
