Paper Abstract

An analysis is made of the effect of birefringence in a sapphire dome on the performance of an imaging system located behind the dome. An incident ray is divided into ordinary and extraordinary ray components and a method is given to trace each component ray to the image plane. The method is applicable to any birefringent dome material with arbitrary crystal axis orientation. It is found that image blurring increases rapidly as the size of the system semi-aperture approaches the dome radius of curvature. There is considerable image blurring even for a small aperture when the crystal axis is not at 0 or 90 degrees from the system optical axis.
