High-resolution inset head-mounted display

摘要

A novel approach to inset superimposition in a high-resolution head-mounted display (HMD) is presented. The approach is innovative in its use of optoelectronic, nonmechanical devices in place of scanning mechanical devices commonly adopted previously. A paraxial layout of the overall HMD system is presented, and the benefit of employing hybrid refractive-diffractive optics for the optical component that generates the inset is discussed. A potential overall HMD design is finally presented to show the integrated system. The practica] limitations of the designed system are discussed and an alternative approach is presented to compare the advantages and the limitations of these systems. # 1998 Optical Society of America OCIS codes: 090.2820,220.0220,050.1380,230.0250.
