This invention uses a Digital Micromirror Device as a scanner to create a novel optical design that expands the field of view as it scans.
About
DMD-Based Optical Scanning Device Tech-ID: UA16-003 Invention: Researchers at the University of Arizona have created a wide field-of-view optical device using a Digital Micromirror Device (DMD) as a scanner. The low-cost, fast-scanning device leverages off-the-shelf optical components to create a novel optical design, which employs tilted mirrors and retro-reflectors to extend the field of view (FOV) while providing a high angular resolution. Background: Conventional Light Detection and Ranging (LIDAR) range finders are costly, often have small fields of view, and can be slow in determining distances with good angular resolution. The development of autonomous vehicles will need to use less complex and costly systems to become practical. Status: issued U.S. patent #10,281,262
