Abstract


With the wide application of image acquisition system , CCD detection system are increasing. The traditional CCD detection system due to the complex structure , higher cost , can not meet the increasingly wide range of application needs . In this paper, a single FPGA - based the miniaturization and economic CCD detection system , to meet the spatial intensity measurement and recognition and processing of the optical signal . In this paper, the basic structure of the CCD detection system . CCD detection system based on a single FPGA hardware circuit schematics , and complete hardware circuit board production and debugging . System FPGA selected Altera's low-cost FPGA chip EP2C20Q240 circuit board using a two-layer board design, implementation, CCD detection system miniaturization and economic goals . FPGA devices to achieve the design of the CCD drive timing pulse , to achieve a single sampling and correlated double sampling control program design, use of FPGA digital signal processing to achieve a correlated double sampling signal processing . FPGA - based programmable features , without changing the external circuit on the basis of the change in the process , select the CCD driving frequency , analog-to-digital converter sampling moment and easy to adjust . Data transfer interface of the system with the host computer using the network transmission scheme , and give full play to the advantages of long-distance transmission of network transmission , remote access, and information sharing , the system uses FPGA-based Nios II embedded processor system , through its application software development, the reliability of the data transmission system between the host computer .
