Design of operation parameters of a high speed TDI CCD line scan camera

This paper analyzes the operation parameters of the time delay and integration （TDI） line scan CCD camera, such as resolution, line rate, clock frequency, etc. and their mathematical relationship is deduced. By analyzing and calculating these parameters, the working clocks of the TDI CCD line scan camera are designed, which guarantees the synchronization of the line scan rate and the camera movement speed. The IL - E2 TDI CCD of DALSA Co. is used as the sensor of the camera in the paper. The working clock generator used for the TDI CCD sensor is realized by using the programmable logic device （PLD）. The experimental results show that the working clock generator circuit satisfies the requirement of high speed TDI CCD line scan camera.
