Title: DMD-based Optical Scanning Device


Invention: Researchers at the University of Arizona have created a wide field-of-view optical device using a Digital Micro Mirror 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 FOV while providing a high angular resolution. 


Background: Conventional LIDAR range finders are costly, often have small fields of view, and can be slow in determining distances with good angular resolution. The promise of autonomous vehicles will need to utilize less complex and costly systems to become practical.
