| Abstract: | A line-scan imaging systm based on the linear array TDI-CCD camera and lens controlled by step motor are presented. By discussing the basic structure and principle of the TDI-CCD camera, the method of synchronization between the lens scanning speed and the camera line-scan speed is obtained. The details of controlling scheme with step motor are analyzed. With EC-11 camera, the scanning and imaging system gives a picture which is discriminable. |
