A helmet-mounted display (HMD) system is proposed operating with holographic optics. The holographic optical element (HOE) reflectors are mounted on or directly coated on a hemispherical visor. These reflectors will, in combination with the eyepiece system, focus the images properly into the eyes. both images will produce a stereoscopic vision which coincides with the see-through image. The images themselves will be realized with an imaging system such as a CRT. The connection with the eyepieces on the helmet will be made by means of optical fibers. The helmet position and orientation have to be detected as required feedback to the image generating system. This project suggests a holographic detection sensor system to achieve the desired results. in Phase I, a design and feasibility study will be accomplished
