Abstract

Laser Power Corporation (LPC) has developed red, green and blue solid state microlasers that can be operated in a direct-write, parallel-scanning projection display architecture to generate full-color images with extremely high resolution. Relative to Helmet Mounted Displays (HMDs), these microlaser displays presently combine a 1000-ft L brightness with 1920 by 1080 resolution and 60 Hz non-interlaced frame rate. In response to the Navy's requirement for an HMD which incorporates true three-dimensionality, LPC has devised a novel system architecture whereby the focal length of an image can be varied on a pixel-by-pixel basis; i.e. in a manner which simultaneously preserves the depth of fidelity of every object within that image. Referred to as Stereoscopic Image Generation with Multifocal Augmentation (SIGMA), this innovative display concept can provide essentially continuous focal depth ranging from less than a meter to infinity. Furthermore, it is compatible with full-color HMD designs either with or without see-through. LPC's overall Phase I/Phase II program encompasses the development and validation of the SIGMA concept, together with an assessment of the psychovisual advantages which can be derived in the context of Naval aviation.
