| Abstract: | The TDI characteristics of CCD camera as a low illumination level night vision detector is described. The real time display technique of the object image after multiple frames accumulation is presented.Using external trigger control system of CCD camera and the EPLD device, the image of a static object when the illuminance of CCD FPA (Focal plane array) less than 3 7×10 -5 lx with resolution of 300TV lines was detected. |
