TI  - Design of an ultralight and compact projection lens.
PG  - 97-107
AB  - Driven by the need for lightweight head-mounted displays, we present the design 
      of an ultralight and compact projection lens for a head-mounted projective 
      display (HMPD). An HMPD consists of a pair of miniature projection lenses, beam 
      splitters, and miniature displays mounted on the helmet and retroreflective 
      sheeting materials placed strategically in the environment. The HMPD has been 
      proposed recently as an alternative modality for three-dimensional visualization. 
      After demonstrating the concept, building a first-generation custom-designed 
      prototype, and investigating perception issues and application potentials, we 
      designed an ultralight and compact projective lens with a diffractive optical 
      element (DOE), plastic components, and aspheric surfaces for the next-generation 
      prototype. The key contribution here lies in the conception, optimization, and 
      assessment of the projection optics. Thus a brief review of the HMPD technology 
      and related research is followed by a detail discussion of the conception and 
      optimization of the ultralight and high-performance projection optics. The design 
      of the DOE will be particularly described in detail. Finally, the diffraction 
      efficiency of the DOE will be evaluated, and the overall performance of the 
      optics will be assessed in both object space for the optical designer and visual 
      space for possible end-users of the technology.
