Paper Abstract

Head- and helmet-mounted displays can benefit greatly from new image generating technologies. This paper describes a liquid crystal digital scanner-based head-mounted display (DS-HMD) that has been developed at Physical Optics Corporation (POC). The HMD consists of low power light emitting diodes (LEDs), a liquid crystal digital scanner, and image projection optics produced by POC's proprietary holography technology. Modulating the individual LEDs while synchronously scanning perpendicularly generates a 2D image. The paper describes design, fabrication, and performance measurements for an actually implemented experimental liquid crystal digital scanner system, and design and fabrication of the holographic components.
