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 practical limitations of the designed system are discussed and an alternative approach is presented to compare the advantages and the limitations of these systems.
