Paper Abstract

At present, CCD is widely applied in many fields. Here, we introduce you a special linear area CCD camera which uses Time-Delay-Integration (TDI) technique to provide high sensitivity, high speed, high spatial resolution and wide dynamic range performance under low light conditions. TDI is a method of scanning which provides greater sensitivity than other video scanning methods, and the interface that it needs is quite different from conventional ones. In the paper, the principle and the features are presented. In order to apply the TDI method and verify the effect, we do an experiment of grabbing moving image through using CT-E1 and CL-E2 2048X96 TDI Line Scan CCD camera produced by DALSA INC.. We design a grabber and make a complete system by ourselves. The system includes: camera, camera control, frame grabber, revolving stage, PC. The result indicates that when the line-shift-rate of the CCD camera is not synchronized with the rate of moving object, the image that we obtain is not clear. But when we use phase-shift- compensation technique and make the line-shift-rate of the camera match the rate of the image, we can get very distinct image.
