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。 With the improvement of technology and manufacturing technology, and the development of space photography technology, the area CCD is more and more widely used in the field of space photography technology. In space photography, often encounter the problem of insufficient illumination. To shoot a clearer image, you have to solve the problem of insufficient energy. Increasing the integration time is one of the solutions to the problem of insufficient energy. In general, increasing the integration time requires image shift compensation. In this article, we present an implementation of a method based on an integrated linear array (CCD) integrated delay (TDI) operation.
