摘　　要：基于FPGA设计了一套数据采集系统,实现某超光谱成像仪研制过程中的光谱图像数据的采集、传输、显示与存储。该设计综合应用了FPGA、USB、LVDS、时钟数据恢复、8B/10B编码、乒乓缓存等技术,具有高速率、低功耗、小型化和轻量化等特点,对类似数据采集系统的设计具有参考和借鉴意义。A set of data acquisition system based on FPGA is designed for a hyperspectral imager to acquire, transfer, store and display the spectral image data in its developing course. The design is technically involved in FPGA, USB, LVDS, CDR, 8B/10B Codec, Ping-pong Buffer etc. While having high speed, low power consumption, small size, light weight and so on, it can be a good reference for similar system design.
