Abstract

A compact, ultra-light and high-performance projection optics lens assembly using Diffractive Optics Technology, plastic and glass optics, and Aspheric optics has been designed with only four elements. The lens may be included as is, or scaled to be included in all instruments using conventional Double-Gauss lens forms. The preferred lens is only 20 mm in diameter and 15 mm long has a weight of only 8 g. Thus, two lenses for head mounted stereo displays is only 16 g. Such a stereo display, known as a head-mounted projective display (HMPD), consists of a pair of miniature projection lenses, beam splitters, and miniature displays mounted on the helmet, and retro-reflective sheeting materials placed strategically in the environment.
