Holographic Lens for Pilot's Head-Up Display

Abstract

This report describes work on the development of a hologram recording apparatus with a fringe control system for 16 in. diameter, 50 degrees off-axis, symmetric transmission holographic lens for pilot's Head-Up Display (HUD). The basic HUD system parameters are a 25 degrees field of view, a 25 in. eye relief, and a 3 in. by 5 in. wide exit pupil. The hologram geometry was chosen based on parametric analysis and preliminary studies on several Hughes continuous reflection and transmission hologram lens designs of Phase 1, Contract N62269- 73-C-0388, Holographic Lens for Pilot's Head-Up Display. The work also includes design of processing equipment for large holographic lens elements recorded on 18 in. x 18 in. dye-sensitized dichromated gelatin, holographic plates. 18 in. x 18 in. x 0.25 in. thick photographic plates were procured under this contract.
