Design of image processing system for UV solar blind focal plane detector

The hardware and software design of an image processing system were discussed based on DSP chip and USB interface chip. The image processing system was designed to acquire and process the outputting analog signals of 128 × 128 UV solar-blind GaN-based focal plane array, and the high-quality scenery image was drawn on personal computer. DSP chip and USB interface chip were used to process and transmit the signals to personal computer, and based on the characteristic the programs was designed for two-dimensional filtering to improve the image quality and double buffer technique to increase the bandwidth of the image processing system. Imaging tests show that the image processing system could work normally and meet the design requirements. While two-dimensional filtering and double buffer technique are applied on the image processing system, the image quality and the system bandwidth are improved.
