电荷耦合器件(CCD)作为一种新型的光电器件被广泛地应用于非接触测量物体尺寸。CCD通过必要的光学系统和适合的驱动电路完成光电转换，将物体在空间域分布的光学图像转换成一列按时间域分布的电脉冲信号。以线阵CCD图像传感器TCD1251UD为例，设计了视频信号预处理电路，并采用可编程逻辑器件FPGA实现积分时间和频率同时可调的CCD驱动程序，完成了对CCD输出信号的数据采集。实验结果证明时序脉冲能够驱动CCD完成光电转换功能，数据采集电路能够采集到需要的信号数据。

Charge Coupled Device (CCD) is used in non-contacted measuring object’s dimension as a new photoelectric device, which can convert optical image of the part in the spatial domain into video signal in the time domain with the aid of the essential optical system and suitable driving circuit. Taking linear CCD image sensor TCD1251UD as example, this paper presents a linear CCD driver design with a Complicated Programmable Logical Devices FPGA, which makes integration time and frequency tuned simultaneously. Video signal processing and data acquisition from the output image signal of CCD were accomplished in this dissertation. The experiment shows that the timing driven pulses could meet the requirement of CCD, the data also could be obtained from the signal acquisition circuit.
