The laser radar in our project used dual imaging channel connected to two ICCD photosensor with different gains. My subject mainly researches the system of data acquisition. My image data acquisition card used Camera Link interface to connect with ICCD photosensors and utilized PCIe bus to upload image data to the computer. Between the two interfaces, I make use of FPGA to control the two interfaces, cache data and upload data. I used DMA mode to transmit data, because it extremely increased the transfer speed and save in CPU resource.
