| Abstract: | This paper develops an imaging system using a Time Delay and Integration line Scan (TDI) IL E2 CCD. The imaging of an object can be shown on CRT of a PC computer. The paper designs the circuits of working clock and power driver for CCD. After adopting the correlated double sampling technique and filtering the reset noise of CCD, the paper enhance the signal to noise ratio of the video signal. The data rate is 10MHz, and the line rate is 3.5kHz. |
