Abstract: A method includes projecting, by a first projector, a first image to a first region, the first image having a first angular resolution and a first number of views. The method also includes projecting, by a second projector, a second image to a second region, the second image having a second angular resolution and a second number of views, where the second region is within the first region, the second angular resolution is greater than the first angular resolution, and the second number of views is greater than the first number of views.

Abstract: A system includes at least one laser configured to produce laser light and an optical element configured to produce shaped light responsive to receiving the laser light. The system also includes an optical phase modulator (OPM) optically coupled to the optical element, the OPM configured to modulate the shaped light to produce modulated light, where the optical element is configured to reduce a point spread function of the modulated light in a far field.

Abstract: An image may be formed in a projection system by forming a light beam with substantially a first polarization. The light beam is directed onto a first color wheel that transmits a first selected color portion of the light beam and reflects a second color portion of the light beam. The reflected second color portion is converted to a second polarization. A first portion of the image is produced with a first spatial light modulator using the first selected color portion of the light beam having the first polarization. A second portion of the image is produced with a second spatial light modulator using at least a portion of the reflected second color portion of the light beam having the second polarization. The first portion of the image and the second portion of the image are combined to form a combined image for projection.

Abstract: An example device includes a screen, a first light source configured to emit a first light at a first angle during a first time period and a second light source configured to emit a second light at a second angle during a second time period. The second angle is different than the first angle. The second time period is different than the first time period. The device includes a spatial light modulator configured to provide a first view of digital content based on the first angle of the first light emitted during the first time period and a second view of the digital content based on the second angle of the second light emitted during the second time period and projection optics configured to project the first view and the second view for presentation via the screen.
