Abstract

In order to monitor the state of control cell of TDI CCD of multi spectrum space optics remote device and test the function and reliability

a novel detection system of CCD signals for space optics system is designed. By using the FPGA

48 clock drivers and 31 DC bias signals are all analyzed and detected simultaneously. At the same time

solutions of the detection are transmitted to PC. All models such as A/D control

logic analysis and UART are integrated in the FPGA. Experiment results show the detection system can exactly monitor the state of the controlling cell of TDI CCD. It totally satisfies the requirements for detection of TDI CCD of multi spectrum space optics remote sensing device.
