Abstract

A high resolution TDI-CCD system with measurement coding is proposed to acquiring high resolution image with the limitation that pixel size is not able to be smaller. The difficulty that enhancing the resolution alone the forward direction and its vertical direction at the same time without the changing of driving circuit and the con is solved by integrating several TDI-CCDs in a system, where each pixel of the TDI-CCD is coded by the measurement matrix. The high resolution image is reconstructed by the acquirement of each TDI-CCD and the measurement matrix in the end. The simulation shows the SSIM of the image acquired by proposed high resolution TDI-CCD system can reach beyond 0.95 in theory.
