Methods and apparatus for angular and spatial modulation of light

A light projection system, including a light source to provide an output beam of light, an angular light modulator (ALM) comprising a plurality of pixels, each pixel having an ON state and an OFF state, the ALM positioned to receive output beam on the plurality of pixels, and a processor coupled to the ALM. The processor is programmed to control a first set of the pixels to transition between the OFF state and the ON state while the beam is incident on the pixels. An amount of light is selectively directed in a direction by the first set. The processor is also programmed to control a second set of the plurality of pixels to remain in the OFF state while the beam is incident on the plurality of pixels. As a result, the ALM operates as a spatial light modulator and an angular light modulator of the beam of light.

High speed binary compressive light field projection system

Implementations of a compressive light field projection system are disclosed herein. In one embodiment, the compressive light field projection system utilizes a pair of light modulators, such as digital micromirror devices (DMDs), that interact to produce a light field. The light field is then projected via a projection lens onto a screen, which may be an angle expanding projection screen that includes a Fresnel lens for straightening the views of the light field and either a double lenticular array of Keplerian lens pairs or a single lenticular, for increasing the field of view. In addition, compression techniques are disclosed for generating patterns to place on the pair of light modulators so as to reduce the number of frames needed to recreate a light field.
