| Abstract: | An imaging driving system based on image sensor FTT1010M produced by DALSA and FPGA for dynamic CCD star sensor is designed and realized. The characteristic and working schedule of FTT1010M, schedule circuit of imaging driving system for star sensor, analog driving circuit, power supply circuit, pretreatment circuit and testing are mainly introduced. Result of experiments show that the designed driving circuit can fit the demand of CCD driving. Exposal time and gain of ADC can be adjusted by computer. Imaging with star simulator, system can acquire clear star image with short exposal time. It shows the system establish foundation for the realization of dynamic CCD star sensor. |
