Paper Abstract

The image quality of a high resolution space camera may be degraded by wavefront aberrations and optical axis jitters. It is desirable to use an in-orbit instrument to measure these errors and then correct them with on-line adaptive optical technologies or off-line image restoration algorithms. An integrated method of measuring wavefront aberrations and optical axis jitters of the space camera based on the ground scene Shack-Hartmann wavefront sensor is studied. When working in jitter-sensing mode, only parts of the sub-images are read to enhance the frame rate. Factors affect the precision are analyzed. Experiments are made which show that this method has a good performance by choosing proper parameters.
