Paper Abstract

There are several disadvantages in existing electronic display systems for spectrometer, such as the images with noise and fuzziness, the cross hair with low sharpness and so on. In order to solve these problems, a new type of electronic display system for spectrometer is designed in this paper, connecting the spectrometer eyepiece to a CCD Camera with a Camera Link interface, and setting up a video processing system platform with a high performance FPGA. The Camera Link signals collected by the front-end system are sent into two pieces of SDRAM. The controller of SDRAM generated on the FPGA realizes data with caching and processing high speed data streams by ping-pong operation. Then the data signals are filtered by filter module generated on the FPGA and the color space of treated signals are converted. In the back-end system, signals encoded by two coder chip are separately outputted through the CVBS and the VGA interfaces. This design solves above problems of the original system.
