Aiming at the decreased image quality due to the exposure time,we propose an interline transfer area array CCD-time delay integral(TDI) light-adjusting method.We choose the interline transfer progressive scan CCD KAI-16000 as the imaging device,design and realize the imaging system using FPGA to control the driving signal mode of the interline transfer progressive scan CCD combined with the normal electronic shutter dimming method and the TDI dimming method.The experimental results indicate that the imaging...
