Research On Area Array CCD Imaging System Based On The FPGA

With the increasing of people’s daily life and national defense scientific research progress, image acquisition technology has been more and more attention and widely used. At the same time, with the development of technology and the reduction of cost, and the real-time data acquisition, parameter, high accuracy, communication etc.,CCD(Charge coupled device)as an important imaging detector, in astronomy, remote sensing, detection and other industrial fields has been widely used, Occupy an absolute advantage in the field of image acquisition. Because of the increased demand for CCD devices, there have been a variety of characteristics and models of CCD, Makes it hard to meet the demand of the standardization and consistency of drive circuit, the hardware operation difficulties of traditional method is flexible and more extensible FPGA substitution.. The CCD drive to a new FPGA.The design of the program area CCD imaging system to be adopted interline transfer program, then analysis, design, and instructions for key electronics unit, Control and processing based on FPGA opposite CCD detector output analog video signal amplitude, bias, gain, integration time and other key parameters.
