基于双单片机的线阵CCD驱动及信号处理系统
Linear array CCD drive and signal processing system based on double-SCM
摘要
Abstract
Two STC11F02 chips are used for the driving and signal processing of linear array CCD device. One generates CCD drive time-sequence signal,and another is responsible for measurement control and communication with the host computer. The CCD output signal is processed with the hardware method to directly obtain the center position of the light spot without A/D conversion. Experimental results show that the measurement precision can reach 0.007 mm. The circuit has the characteristics of low cost,small size,high speed,and can be widely used for non-contact geometry measurement based on linear array CCD.关键词
