Abstract
This application relates to a see-through head-mounted display using recorded substrate-guided holographic continuous lens (SGHCL) and a microdisplay with narrow spectral band source or laser illumination. The high diffraction efficiency of the volume SGHCL creates very high luminance of the virtual image.
Claims20
A holographic substrate-guided head-mounted see-through display comprising:
- (a) an image source comprising a microdisplay with narrow spectral band illumination;
- (b) an edge-illuminated transparent substrate, and;
- (c) a single volume holographic lens.
A method of recording a volume holographic lens comprising shining two spherical beams onto a holographic polymer index-matched to a substrate, wherein a first recording beam is guided from an edge of the substrate and convergent to a first focus point and a second recording beam is divergent from a second focus point, and wherein both beams cover the holographic polymer.
