| Abstract: | The reliability and the ability of anti irradiation of CCD is concerned in the lifetime of CCD camera.The drive method and the restrain method of output DC level are concerned in whether or not the capacity of CCD is made well.In this paper use the data acquired from the speeding up lifetime test,estimating the reliability of CCD,analyzing the influence of high energy irradiation on CCD device.On the other hand,analyse the analogy and digital drive,compare the two methods of restraining output DC level and raise an anti electrostatic method. |
