Abstract

Combat vehicles of the future may be devoid of direct vision ports but will contain multiple displays creating a virtual environment. The transition from real to virtual can be facilitated by the use of a helmet-mounted display (HMD) that projects a portion of the virtual environment over the real world. The authors propose a simple, light-weight color stereo projection system that has the potential for meeting most of the desired characteristics at a reasonable cost. Imaging is accomplished using CR39 ophthalmic substrates off- axis 15 deg and distorted to correct for astigmatism. The images from two sources are transferred to the focuses by coherent fiber image conduit shaped at one end to minimize field curvature. The demonstrated field of view (FOV) is 15v X 40h deg using readily available image conduit and colored transparencies; maximum FOV is 60v X 90h deg.
