Holographic display systems with polarization correction and distortion reduction providing enhanced image quality

A holographic display system,

• a light source configured to generate a first light beam;
• a holographic projector including a spatial light modulator configured to adjust phases of respective portions of the first light beam to generate a phase hologram beam;
• a beam splitter configured to receive and split either the phase hologram beam or a filtered version of the phase hologram beam to provide a first portion of light and a second portion of light, the filtered version is received from a polarizer filtering the phase hologram beam, and the beam splitter is configured to direct the second portion of light at a diffuser to generate a holographic image;
• a wavefront sensor configured to detect phases of the first portion of the light and generate a phase detection signal, wherein the phase detection signal indicates the phases;
• and
• a control module configured to adjust voltages at pixels of the spatial light modulator based on the phases of the phase detection signal.

A holographic display generation method comprising:

• generating a first light beam via a light source;
• adjusting phases of respective portions of the first light beam via a spatial light modulator to generate a phase hologram beam, wherein the phase hologram beam comprises a first polarization and a second polarization;
• filtering out light having the first polarization from the phase hologram beam via a polarizer to provide a filtered phase hologram beam, wherein the filtered phase hologram beam includes light with the second polarization and does not include light with the first polarization;
• splitting, via a beam splitter, the filtered phase hologram beam to provide a first portion of the filtered phase hologram beam and a second portion of the filtered phase hologram beam;
• detecting, via a wavefront sensor, phases of the first portion of the filtered phase hologram beam and generating a phase detection signal, wherein the phase detection signal indicates the phases;
• adjusting, via a control module, voltages at pixels of the spatial light modulator based on the phases of the phase detection signal;
• and
• providing the second portion of the filtered phase hologram beam to a diffuser to generate a holographic image.
