摘要
研究了彩色显象管曝光台光电检测系统中，采用多片线阵ＣＣＤ实现显象管曝光台８个特征点水平微小位移实时同步测量的方法，给出了ＣＣＤ工作参数和输出电路设计。为了避免采用高速Ａ／Ｄ和ＤＭＡ方式，而又确保系统的实时性和精确性，针对给定的数据处理特性，本文对ＣＣＤ的信号处理采用高精度的电压／频率转换。该系统测量精度达３μｍ。
A method for real time measuring horizontal displacement of color kinescope exposure platform by multiple CCDs synchronous sampling in photoelectronic measuring system is presented in this paper.CCD operating parameters and the design of output signal processing circuit are given. In order to avoid using high speed A/D and DMA mode,and ensure the timeliness and accuracy,high precision F/V is adopted for the given characteristics of data processing,and the accruacy of 3μm can be achieved.
