Abstract
Ghost images are caused by both specular and scattered reflected rays from optical surfaces and are always unwanted, especially within the image format of the scanned field image plane. This paper illustrates the formation of stationary ghost images that are produced only by the reflected rays from the image plane itself. A large portion of these rays are directed back through the optical scanning system to the mirror-facets of a prismatic polygonal scanner, which returns them to form one or more stationary ghost images in the image plane. The goal is to determine the angular ranges of incident beam offset angles from the scan-axis that ensure that the ghost images lie outside the image format.
