OPTICAL PHASE MODULATION SYSTEM, AND DISPLAY DEVICE

WIPO Patent Application WO/2023/100511

A1

An optical phase modulation system of the present disclosure comprises: an illumination light projection unit that is configured to enable polarization control in which the directions of the polarization of light projected as illumination light are set to a first polarization direction and a second polarization direction different from the first polarization direction, and that is configured to enable the light in the first polarization direction and the light in the second polarization direction to be projected at mutually different timings and in mutually different directions; a phase modulation unit having a first area configured to enable phase modulation of the light in the first polarization direction from the illumination light projection unit, and a second area configured to enable phase modulation of the light in the second polarization direction from the illumination light projection unit; and a synchronization controller that synchronizes the timing at which the light in the first polarization direction and the light in the second polarization direction are projected from the illumination light projection unit and the timing of the phase modulation of the first and second areas of the phase modulation unit.
