Field Steering ASLM
Title: Field Steering ASLM Invention: Researchers at the University of Arizona have developed an apparatus and means of using DMDs and DLP chips in more than just a binary manner. The novel apparatus and means produces a spatial light modulator that also acts as an angular light modulator. One set of embodiments allows an entire field of an image to be steered for illumination or detection. Background: The Digital Micromirror Device (DMD) is a type of Spatial Light Modulator (SLM) composed of an array of micromirrors. Each mirror, acting as a pixel in a display, is a binary switch rotating between two states located at +12 degrees and -12 degrees (specific product dependent), effectively “on” and “off” states. The DMD is typically used as a binary device. Applications:* LiDAR* Beam steering Advantages:* High speed with a wide angular range* Inexpensive compared to conventional devices Contact: Amy Phillipsamyp@tla.arizona.eduRefer to case number UA18-078
