Abstract

Design of image intensifier night vision systems involves meeting the typical requirements of a high aperture and high-speed objective with high contrast at low frequencies throughout the image field. Use of conventional homogeneous lenses in such systems often gives rise to bulky structures in size and weight. In this paper, we describe the availability and use of gradient index (GRIN) materials that have a great potential to reduce the size and weight of such complex systems. However, we restrict ourselves to the use of commercially available axial GRIN materials for the current application in order to demonstrate realizable GRIN night vision systems.
