Abstract: When designing wide field of view tactical or scientific infrared systems, the performance requirements often demand that a large aperture, diffraction limited telescope be specified. In such cases, it is often difficult to maintain a flat focal plane and to limit the image plane size to match an existing infrared focal plane array technology. In this paper the design of an optical system containing a coherent infrared fiber bundle is described. The advantages of reformatting a curved liner image plane to match a planar 2-D focal plane array are discussed. To validate the design concepts, a 12 channel fluoride fiber was employed to relay the image of a Schmidt Telescope to a remotely located detector array. A comparison of predicted system performance and measured system performance is presented. !3
