S20-531 Resonant Scanning Design and Control for Fast Spatial Sampling Despite their compact form factor and low power consumption, resonant scanners have not been widely applied to LiDAR due to their scanning trajectory. Zhanghao Sun Ron Quan Olav Solgaard Sandra Manosalvas-Kjono
S20-278 Tunable, On-Chip Beamsteering with Resonant, Electrically-Reconfigurable Phase Gradient Metasurfaces The Dionne lab has developed ultrathin and compact devices for electrically driven beamsteering that fit on a semiconductor chip. These devices rely on resonant dielectric nanostructured surfaces known as "high quality factor" (high-Q) metasurfaces. Jennifer Dionne Mark Lawrence David Barton Elissa Klopfer Sahil Dagli
