Research on data acquisition and transmission system of frame transfer area array CCD based on USB 2.0

The software and hardware of a data acquisition and transmission system in regard to the frame-transfer area array CCD based on USB2.0 are concerned in this paper.A driven timing generator based on field programmable gate array(FPGA) for CCD has been designed.The system takes use of a dedicated video processing chip for CCD sampling,quantizing the output analog signal of CCD and converting them into digital signal.It can achieve fast and accurate data transmission through the USB 2.0 interface,which was connected with a computer.
