Abstract
A holographic display apparatus includes: a light source; a spatial light modulator configured to modulate light from the light source according to an image to be displayed on an object plane; and a processor configured to generate a computer generated hologram (CGH) in which a phase value of hologram data to be displayed on a reference plane of the spatial light modulator is 0, the processor being configured to apply a light modulation signal based on the CGH to the spatial light modulator.
Claims27
A holographic display apparatus comprising:
- a light source;
- a spatial light modulator configured to modulate light from the light source according to an image to be displayed on an object plane;
- and
- a processor configured to generate a computer generated hologram (CGH) in which a phase value of hologram data to be displayed on a reference plane of the spatial light modulator is 0, the processor being configured to apply a light modulation signal based on the CGH to the spatial light modulator.
A holographic display apparatus comprising:
- a coherent light source;
- an amplitude modulation spatial light modulator (SLM) configured to modulate coherent light incident from the coherent light source;
- and
- a processor configured to:
- receive object amplitude data of an image to be displayed at an object plane;
- calculate object phase data of the image to be displayed at the object plane such that reference phase data of a computer generated hologram (CGH) applied to the amplitude modulation SLM is substantially equal to zero;
- generate the CGH comprising the reference phase data;
- and
- apply the CGH to the amplitude modulation SLM to display the image at the object plane.
