At present

CCD is widely applied in many fields.Here

we introduce you a special linear area CCD camera which use Time-Delay-Integration(TDI) technique to provide high sensitivity

high speed

high spatial resolution and wide dynamic range performance under low light condition.In order to apply the TDI method and verify the effect

we do an experiment of grabbing moving image using CT-E1 2048X96 TDI Line Scan CCD camera produced by DALSA INC..We design a grabber and make a complete system .Which includes: Camera

Camera Control

Frame Grabber

Rolling platform

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.
