Abstract: An apparatus includes a focusing lens, a SLM optically coupled to the focusing lens and comprising micromirrors on a surface of the SLM, where the focusing lens is tilted at an incident angle relative to the surface of the SLM, an incident light beam is illuminated on the SLM at the incident angle, and the incident angle is greater by an offset angle than twice a tilt angle of the micromirrors with respect to the surface of the SLM. The apparatus also include an actuator optically coupled to the SLM, and projection optics optically coupled to the actuator.

Abstract: An apparatus includes an image sensor, a linear actuator, a projector coupled to the linear actuator, and a controller coupled to the image sensor and to the linear actuator. The controller is configured to determine a location of an eye of a user based on image data from the image sensor. The controller is further configured to activate the linear actuator to drive the projector to a position associated with projecting to the eye at the location. The controller is further configured to initiate projection, via the projector, of an image depicting a view of a three-dimensional scene, the image selected based on the location.

Abstract: An apparatus includes a spatial light modulator (SLM) having a first region and a second region and a phase light modulator (PLM) optically coupled to the SLM. The PLM is configured to receive first light having a first color and receive second light having a second color, the second color different than the first color. The PLM is also configured to direct the first light towards the first region of the SLM and direct the second light towards the second region of the SLM.

Abstract: An apparatus for high dynamic range (HDR) modulation includes one or more lasers configured to transmit respective beams of laser light with a single color mode and a PLM optically coupled to the one or more lasers. The PLM is configured to modulate the laser light to produce a first modulated light. The apparatus also includes a phosphor optically coupled to the PLM and configured to receive at least a first portion of the first modulated light from the PLM and to emit a phosphor light with multiple color modes. At least one spatial light modulator (SLM) is also optically coupled to the phosphor and configured to modulate the multiple color modes in the phosphor light and the single color mode to project a second modulated light.

Abstract: In an example, a system includes a light splitter configured to reflect first light having a first wavelength and a first polarization, to transmit light having the first wavelength and a second polarization, to transmit light having a second wavelength, and to transmit light having a third wavelength. The system also includes a quarter wave plate optically coupled to the light splitter. The system includes a color wheel optically coupled to the quarter wave plate, the color wheel having a first filter segment, a second filter segment, and a third filter segment. The system also includes a phosphor optically coupled to the color wheel, the phosphor configured to produce second light responsive to receiving the first light, and the color wheel configured to receive the second light and produce light having the second wavelength or the third wavelength.

Abstract: A method includes determining a first location, within a first viewing window, of a first eye of a user based on image data from an image sensor. The first viewing window corresponds to a first projector of a plurality of projectors. The method further includes determining a second location, within a second viewing window, of a second eye of the user based on the image data. The second viewing window corresponds to a second projector of the plurality of projectors. The method further includes initiating projection, via the first projector, of a first image depicting a first view of a three-dimensional scene. The first image is selected based on the first location. The method further includes initiating projection, via the second projector, of a second image depicting a second view of the three-dimensional scene. The second image is selected based on the second location.
