In order to collect scientific data of lunar-based extreme ultraviolet camera
generate images
and display these images in real-time
a display system of lunar-based extreme ultraviolet camera is designed. This system adopts FPGA of XILINX Virtex II series as the image acquisition
processing and control core. It has the functions of receiving scientific data
generating and storing the image data
as well as controlling USB interface. The system can communicate with extreme ultraviolet camera based on RS-422 interface
and receive scientific data by LVDS interface. The image data is transmitted to computer through USB bus. And the computer can generate images and display these images in real-time. Imaging experiment
using this system and the extreme ultraviolet camera
has been done. The result of this experiment shows that the system can correctly collect scientific data
generate image data and display image when the photon counting rate is 66 kcps.
