Abstract

Abstract: The principle of causing the pixel response nonuniformity of CCD and the problems of CCD application are researched. An improved normalization algorithm is used by the method. Because of the arts and crafts, every pixel of charge coupled device has a different sensitivity. This problem can be solved by this algorithm. And the source error can be reduced effectively. It has a great significance to improve the measurement accuracy of CCD.

Key words: Charge coupled device, Image sensor, Sensitivity, Nonuniformity
