Abstract: An image decoding system provides a phase pattern encoding a target image. A spatial light modulator is configured to emit a wavefront-shaped light signal based on the phase pattern. A first diffusive medium receives the wavefront-shaped light signal and emits a decoded scattered light signal of the target image. The target image is previously encoded in the phase pattern by transmitting another wavefront-shaped light signal shaped by a training phase pattern through a second diffusive medium to yield a scattered light signal encoding a test image. The second diffusive medium has the optical scattering characteristics of a first diffusive medium. The scattered light signal encoding the test image is emitted from the second diffusive medium and recorded. The training phase pattern is adjusted for successive iterations of the test image until the test image satisfies a compensation condition. The resulting training phase pattern yields the phase pattern.

Abstract: Methods, systems, apparatuses, and computer program products are provided for a backlight assembly for a display device. The backlight assembly includes a transparent waveguide layer, a plurality of light sources, and a tunable grating layer. The light sources are arranged along an edge of the waveguide layer. Each light source transmits light into the waveguide layer through the edge. The grating layer is coupled to the waveguide layer, and has multiple rows. Each row of the grating layer is segmented into a series of cells so the grating layer is sectioned into an array of cells. Each cell is independently controllable to either not extract incident light received from within the waveguide layer, or to extract the incident light for emission from the backlight assembly. In another configuration, the waveguide layer is not present, and the light sources transmit light directly into an edge of the grating layer.
