Abstract

Abstract

In order to ensure the imaging quality of sweep aerial remote sensor, the precise assembling of TDI CCD is researched. Firstly, the working principle of sweep aerial remote sensor and TDI CCD is introduced. Secondly, degradation in the Modulation Transfer Function(MTF) of TDI CCD caused by the angle between TDI direction of TDI CCD and image motion in the direction of pendulum swing is discussed. And the calculated results demonstrate that precise assembling is indispensable to TDI CCD in sweep aerial remote sensor. Finally, the method of precise assembling of TDI CCD in sweep aerial remote sensor is provided. The assembling and adjusting results show that the assembled method of TDI CCD can give very high precision, and the MTF at Nyquist frequency of TDI CCD caused by the assembling error is 0.999 9, when the stages of TDI CCD are 200.
