<title>Optical-correlator-based system for the real-time analysis of image motion in the focal plane of an Earth observation camera</title>

Abstract

The paper describes the design concept of an optoelectronic system for real time image motion analysis. The system is proposed to be used onboard an Earth observation satellite for the real time recording of the image motion in the focal plane of the camera. With this record available, it is possible to use pushbroom scan cameras onboard satellites with moderate attitude stability (possible geometric distortions, caused by the attitude instability, can be corrected posteirori on base of the records). New experimental results are presented, which have been derived from a real-time breadboard model of the optical processor, developed and manufactured under ESA- contract. The results of the tests are provided as well as the expected performances of a full scale system.
