Paper Abstract

The wave shape of CCD output signal, on the one hand, reflect the result of synthetic influence between CCD itself and the parts before it. On the other hand, it reflects the degree of difficulty to derive and process signals for the circuits after it. Thus, relative factors affecting measurement accuracy can be known by analyzing the CCD wave shape. This analysis not only built the foundation for measuring total error of the system, but also obtained some important designing parameters. Basis can be provided for definite relative parameters in the case of whole system designing. It can be known from the analysis that slope of the wave shape and its amplitude difference (Delta) Vs directly influence deriving the CCD signal. It also affect the measurement accuracy of the system. (Delta) Vs also relates to the number of photoelements m passed by image during the period of CCD photo-integral.
