Abstract
An optical relay () includes a glare trap () that in one embodiment has one or more surfaces configured to reflect light impinging the surface () at an angle less than a first angle () relative to a normal line (), and to transmit light impinging the surface () at an angle greater than a second angle () relative to the normal line (). In other embodiments, the glare trap () reflects light impinging at an angle greater than a first angle and transmit light impinging at an angle that is less than a second angle. The separation between the first angle () and second angle () can be on the order of 20 degrees or more, but this angle can be reduced or eliminated when polarized light is used within the optical relay ().
