About
Angular Spatial Light Modulator (ASLM) Tech ID: UA17-156 Invention: This invention is an Angular Spatial Light Modulator (ASLM) using a novel arrangement of illumination and digital micromirror 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 (the distribution of light on a single plane) and angularly (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 1,000 times smaller than a spatial light modulator. Therefore, a solution is needed to modulate both the angular and spatial domain without creating a bottleneck. Status: issued U.S. patent #11,223,805
Key Benefits
- Much higher angular and spatial modulation rates - Less expensive than mechanical scanners - More compact than mechanical scanners - More rugged and less vulnerable to failure
Applications
- LIDAR - Virtual reality or augmented reality displays - Projectors
