Study On Interface Of High Frame Frequency Camera Based On Hartmann-Shack Sensor

With the Hartmann-Shack Sensor used in exact test field widely, the research about interface of high speed, high-powered digital CCD camera become trend. The high speed I/O interface of FPGA support a new scheme about the design about interface of camera, that finished rate matching use programmed technology in digital.For realizing the driver design for high speed figure, the remote high speed data collect and real time high-capacity data stores, the system has adopt a lot of new technology. In this system, the FPGA made of Altera is used to design the logic about interface. LVDS interface is used between the high speed figure and FPGA, speed up to 120MB/S, distance amounts to 100m used CAT5.In this system, USB miocrocontrolor made of Cypress is used to transmit data by usb2.0 rate, to achieve display of data and real-time storage. It is speed rate to 480MHz, ensured the integrality of image data commendably.
