Motion of the image presented to an electro-optical imaging system blurs the incoming energy and degrades the systems ability to detect or recognize distant targets. This paper addresses the effects of image motion on the performance of electro-optical imaging systems and investigates alternate methods of specifying the allowable image motion for the stabilization system. Specifically, the effects of both the spatial and temporal frequency content of the motion spectrum on the system MTF (Modulation Transfer Function) and on the systems ability to recognize and detect distant targets are discussed. Types of image stabilization specifications considered include RMS jitter amplitude, maximum allowable motion amplitude during an integration interval, allowable MTF degradation and allowable motion versus temporal frequency. These are then compared according to (1) whether or not they can be readily measured, (2) whether they can be easily understood and converted to meaningful design parameters and (3) whether they inadvertently over-constrain or under-constrain the design.
