Light from an array of laser light sources are spread to cover the modulating face of a DMD or other modulator. The spread may be performed, for example, by a varying curvature array of lenslets, each laser light directed at one of the lenslets. Light from neighboring and/or nearby light sources overlap at a modulator. The lasers are energized at different energy/brightness levels causing the light illuminating the modulator to itself be modulated (locally dimmed). The modulator then further modulates the locally dimmed lights to produce a desired image. A projector according to the invention may utilize, for example, a single modulator sequentially illuminated or separate primary color modulators simultaneously illuminated.

In one example, a method comprises forming a first layer on a substrate surface, forming an opening in the first layer, forming a second layer on the first layer and in the opening, and forming a photoresist layer on the second layer, in which the photoresist layer has a first curved surface over a first part of the first layer and over the opening. The method further comprises etching the photoresist layer and a second part of the second layer over the first part of the first layer to form a second curved surface on the second part of the second layer, and forming a mirror element and a support structure in the second layer, including by etching a third part of the second layer and removing the first layer.

A light projection system comprising a light modulator that comprises a plurality of pixels each capable of selectively directing a corresponding modulatable amount of light, and a processor coupled to the light modulator to control the amount of light output from each of the plurality of pixels. The processor is configured to control the light modulator to form a computer generated hologram (CGH) wavefront from the light modulator corresponding to an image to be produced in the far field. The processor is also configured to control the light modulator to selectively direct the CGH wavefront. The light modulator may comprise an angular light modulator (ALM) comprising the plurality of pixels, each of the plurality of pixels having an OFF state and an ON state, the ALM arranged to direct the amounts of light in the direction as the pixels transition between the ON state and the OFF state.

Described examples include an apparatus having a substrate with a substrate surface. The apparatus also includes an element with a planar surface facing the substrate surface and with a nonplanar surface opposite the planar surface facing away from the substrate surface.

The disclosure provides a multifocal display device, comprising a display configured to generate an image, and a controller configured to control the display according to a bit sequence provided over a determined time period to generate the image with one or more colors. The bit sequence includes for each color a subsequence of bits of different significance. Neither the first bit nor the last bit of the subsequence for the respective color is the most significant bit of the subsequence.
