Hign Resolution, Long Linear CCD Driving And Signal Processing Technology Study

This paper introduced the working theory of the CCD and analyzed the noises of the CCD. Based on them, some measures of CCD driver timing were bringed forward The virtue of using FPGA as timing producer were especially introduced. The method of using theory chart and vhdl produced the timing was analyzed; The principle and processing of using XRD98L56 control the Resetting noise and dark current noise were introduced. The system used PCI bus to interface with computer. This paper introduced hardware composing of data collection card based PCI bus and explained problems of using PCI9052 as the bridge chip. VxD is a kind of Windows driver programs, we will specially introduced several important parts and give the program codes. At last, the system'merit and demerit were summarized, step further is put forward.
