A Tutorial on Exit Pupils and Eye Rotation with Virtual Image Optical Displays
Abstract
Exit pupils of virtual image optical displays and eye entrance pupils and how their sizes and relative positions influence light input to the eye are discussed. Equations based on simplifying assumptions about the eye and its rotational behavior are derived and graphed to describe the position of the center and edge of the eye entrance pupil after eye rotation and for the rotation angles at which exit pupil vignetting begins and at which vignetting is total. The graphs and equations are useful for descriptive purposes and for practical application in choosing, specifying or designing virtual image optical display devices. Worked out numerical examples are supplied to further aid in understanding pupils and eye rotation and how they interact. The reader is not required to have a background in optics or in college mathematics.... Displays, Eye relief, Pupils, Entrance pupils, Eye rotation, Vignetting, Exit pupils, Optics.
