Design and realization of CCD array drive circuit

Based on the application principle of the micro-computer, a design and realization method of the CCD array drive circuit which can be applied in angle and displacement measurement is introduced. The CCD array is adopted as a optical-eletricity convertor in the circuit and is controlled by the micro-computer. The sensitivity variable and high accuracy measurement of the angle and displacement is realized for the CCD signals are output by the comparator. The hardware design and program block diagram are given in the paper.
