Paper Abstract

The Reflective Four-Sided Pyramid can be used to divide one light beam into four beams in image space and to achieve the joint purpose of the four CCDs. It also causes the vignetting effect in the joint areas of the image. The calculation of the vignetting distribution caused by the Reflective Four-Sided Pyramid can give us the theoretical basis to guide the further work of image stitching and image luminance processing.
