Study CCD Image Motion for Remote Sensing Detection

摘要

For remote sensing to measure upper atmospheric wind field by optical passive method on-load satellite, the emission source is used of crepuscular aurora of OH 732.0nm. The time of exposure is need about 9sec by remodel Sagnac interferometer, so there is a larger image motion on CCD and the measurement precision is limited. This paper has been calculated the CCD image motion quantity based on remodel pushbroom model by Sagnac interferometer. The MTF curve is demonstrated the image motion can be compensated. Then the techniques of TDICCD, the whole frame transfer, swing mirror and photon memorizer to use compensate the image motion quantity.
