Paper Abstract

Compared with ordinary linear CCD, one of the most remarkable advantages of TDI/CCD is that it can work under low illumination conditions with imaging clearly. Meanwhile, multiple exposures can reduce pixel inconsistency and the fixed-pattern noise; enhance the Sensitivity and Uniformity of visible light CCD. As a result, TDI/CCD has an extensive application in the aerospace industry. To meet the needs of orientation of TDI/CCD's application towards high-speedy, miniaturization and intellectualization, in this paper,Fairchild Imaging CCD525 is chosen as image sensor,by means of programming on XC2V1000 which is one type of Virtex-II serials FPGA, using the key technology such as IP reuse,DCM and timing constrain, realized the functions of real-time adjustment of TDI integration time,number of integration stages,VGA gain and digital quantitative deviation. The whole system not merely passed the software simulation on ModelSim,and achieved satisfactory effect in practical application.
