A method and apparatus for filtering noise for a holographic display are provided. The noise filtering apparatus includes a first filter implemented using a volume grating for filtering DC noise in light modulated by a spatial light modulator or a second filter implemented using a volume grating or a thin-film filter, which filters high-order noise in the light.

Method and apparatus for filtering noise for holographic display

A holographic display apparatus and a hologram optimization method for the apparatus are provided. The holographic display apparatus includes a focus-forming optical element configured to form a plurality of foci by receiving plane waves; a collimating lens configured to propagate, as plane waves, light incident through the plurality of foci; and a spatial light modulator configured to generate a holographic image by overlapping a plurality of plane waves incident from the collimating lens.

Holographic display apparatus and hologram optimization method therefor

Provided is a waveguide-type display device including a waveguide, an input coupler provided on the waveguide and configured to transmit an image to travel into the waveguide, an output coupler provided on the waveguide and configured to output the image traveling in the waveguide to an outside of the waveguide, and a field-of-view (FOV) expander configured to output an image having an expanded FOV by deflecting and outputting the image output from the output coupler in a certain direction based on polarization characteristics of the image.
