摘　　要：随着工艺技术和制造技术提高,以及航天摄影技术发展,面阵CCD越来越被广泛地应用于航天摄影技术领域。在航天摄影里,经常遇到光照度不足的问题。要想拍摄一幅比较清晰的图像,就必须解决能量不足的问题。增加积分时间是解决能量不足问题办法之一。通常,增加积分时间就需要进行像移补偿。在本文里,将介绍一种基于面阵CCD积分延时(TDI)工作方式的实现方法。Following the improving of craft technology and manufacture technology,with the development of Space Photograph,Area CCD are more and more widely applied in Space Photograph.We often meeting the question of being short of illumination in Space Photograph.If want to capture good quality images,we must resolve the question of lacking energy.Increasing the time of exposure is one of the ways on resolving the question.Usually we should use the technology of image motion compensation with increasing the time of exposure.The way to realize time delay and integration based on area CCD is introduced.

关 键 词：面阵CCD 积分延时 像移补偿 航天摄影
