Abstract

At the German Aerospace Center (DLR), within the department Optical Information Systems, investigations are currently being performed on time delay and integration charge coupled devices, with respect to their applicability on satellites for earth observing missions. This paper contains first results of dynamic measurements of point spread function and modulation transfer function of a sensor with 9000 pixels and 64 time delay integration steps. The influence of a mismatch between the line synchronisation frequency and satellite ground speed, as well as the effect of angle misalignment between satellite flight direction and the orientation of the sensor itself onto point spread function, and modulation transfer function was investigated. The performance of the test equipment will also be presented.
