Abstract

Physical Optics Corporation (POC) proposes to continue developing the Parallel Reconfigured Line Image Scanning Miniature (PRISM) display to meet U.S. Air Force needs for a super-high-resolution, compact, full-color, ejection safe, and see-through helmet-mounted display (HMD). Based on our successful development of the Phase I light engine module, POC proposes a superhigh-resolution (~4kx3k), ejection-safe, ergonomic, inexpensive (30 Hz), high-contrast (1000:1), display with wide dynamic range (4-5,000 fL) brightness for day/night vision, wide field-of-view (>80 degrees). POC s approach is based on an advanced design integrating separate lower-resolution frames generated by fast liquid-crystal-on-silicon (LCOS) chips into a superhigh-resolution image by frame transformation. The frames are transformed by RGB holograms along with a MEMS-based scanner to complete high-resolution images. In Phase I we successfully demonstrated the feasibility of the PRISM display in the monochrome regime. Our Phase II efforts will focus on integrating a LCOS with an RGB light source, image transformation element, miniature scanner, and compact projection optics into a flyable brassboard prototype, a ready-for-commercialization superhigh-resolution (>2.5k x 2k pixel) HMD superior to existing technology and compatible with the HGU55/P standard helmet.
