Abstract

Along with the gradual development of CCD-star sensor, exactly extracting star point has been becoming more and more important. The background noise of CCD will affect the extracting accuracy badly. The baffle designed in the old way couldn’t satisfy the high precision requirement of CCD-star sensor nowadays. A kind of optimum baffle design method is expounded in this article. The old design of baffle uses vanes to absorb and attenuate the stray lights, which would be eliminated by scattered and absorbed in the baffle. Whereas, in new method reflex surfaces would replace vanes, the light would be removed by reflected and absorbed.
