Abstract: Example embodiments provide systems and methods for correcting non-uniformities of a light beam generated by a multi-emitter light source. In some embodiments a phase modulator displays patch lenses to correct for the non-uniformities. In some embodiments each region of the phase modulator is illuminated by a beam generated by one emitter of the multi-emitter light source. Such region of the phase modulator may display a patch lens for correcting non-uniformities in the corresponding beam which illuminates the region.

Abstract: Efficient light steering systems and methods. An example method for steering light for a projector system includes illuminating an active surface of a light steering module. The active surface of the light steering module may include a plurality of individually controllable pixels. The method may also include determining a target steering phase pattern for each of a plurality of distinct regions of the active surface of the light steering module. The method may also include controlling the light steering module according to the corresponding target steering phase pattern for each region to increase light steering efficiency.

Abstract: A hybrid projector architecture combines steered light with unsteered light. In some embodiments the steered light is narrowband light and the unsteered light is broadband light. Splitting between the steered and unsteered light may be determined based on luminance level. For example, the unsteered light may contribute a large proportion of the light for luminance levels up to a threshold. The steered light may contribute an increasing proportion of the light as luminance values rise above the threshold.

Abstract: A new projector design combines one spatial light modulator that affects only the phase of the illumination, and one spatial light modulator that only affects its amplitude (intensity). The phase-only modulator curves the wavefront of light and acts as a pre-modulator for a conventional amplitude modulator. This approach works with both white light and laser illumination, generating a coarse image representation efficiently, thus enabling, within a single image frame, significantly elevated highlights as well as darker black levels while reducing the overall light source power requirements.

Abstract: Light projection systems and methods may comprise combining light from two or more projectors. Each projector may be controlled so that the combined light output of the projectors matches a target for the projected light. In some embodiments optimization is performed to generate image data and control signals for each of the projectors. Embodiments may be applied in image projecting applications, lighting applications, and 3D stereoscopic imaging.

Abstract: Image display apparatus and methods may use a single imaging element such as a digital mirror device (DMD) to spatially modulate plural color channels. A color channel may include a light steering element such as a phase modulator. Steered light from a light steering element may be combined with or replaced by additional light to better display bright images. These technologies may be provided together or applied individually.
