Abstract
A holographic lens and a display apparatus using the same as a combiner, the holographic lens including a phase profile obtained through an optimization process for each position to form an imaging optical system for forming a virtual image of lights emitted from a plurality of areas.
Claims26
A holographic lens comprising:
- a plurality of positions configured to form an imaging optical system that images lights emitted from a plurality of areas of a light emitting device on a corresponding plurality of virtual image points;
- and
- a phase profile obtained through an optimization process for each position of the plurality of positions.
A display apparatus comprising:
- an image-providing device configured to provide an image;
- and
- a combiner configured to combine the image emitted from the image-providing device and an external foreground,
- wherein the combiner comprises:
- a holographic lens having a plurality of positions configured to form an imaging optical system that images lights emitted from a plurality of pixels of the image providing device on a corresponding plurality of virtual image points;
- and
- a phase profile obtained through an optimization process for each position of the plurality of positions.
