Angular Spatial Light Modulator (ASLM)

Detailed Technology Description

Title: The Angular Spatial Light Modulator (ASLM) Background: The invention is an Angular Spatial Light Modulator (ASLM) using a novel arrangement of illumination and digital micro-mirror devices (DMDs). The invention can simultaneously modulate spatial and angular content of light with a potential total bandwidth of 1Tera pixel-angle per second (1G in space and 1K in angle). Background: Optical systems control light spatially and angularly, with spatial describing the distribution of light on a single plane and angular describing the propagation of light between planes. The current means of controlling light through the angular domain is limited because it relies on a motorized scanning mirror with a data rate 1000 times smaller than a spatial light modulator. Therefore, a solution is needed to modulate both the angular and spatial domain without creating a bottleneck. Applications:LidarVirtual reality or augmented reality displaysProjectors Advantages:Much higher angular and spatial modulation ratesLess expensive than mechanical scannersMore compact than mechanical scannersMore rugged and less vulnerable to failure Licensing Manager:Amy PhillipsAmyP@tla.arizona.edu
