Abstract
Reflective Micro Electro Mechanical System (MEMS) display as a spatial light modulator with synchronized nano-second pulse effectively diffracts light into one of multiple diffraction orders with high efficiency. Beam and image steering in a time sequential manner by this principle is applied for optical systems such as lidar, near-to-eye display and high-framerate cameras. We overview diffractive MEMS based beam and image steering by using a concept Time-to-Angle Conversion.

Yuzuru Takashima is a tenured full professor at James C. Wyant College of Optical Sciences of University of Arizona. His research focus is MEMS-based lidar for automotives and AR near to eye displays, as well as optical design and metrology of space optics. Prior to joining the University of Arizona, he was a research staff at Stanford University where he conducted research and development of high-density holographic data storage systems and nano-photonic electron beam generators. He was employed as an optical engineer at Toshiba Corporation in Japan and developed ultra-precision manufacturing process for optical components. He is a fellow of SPIE and senior member of OPTICA. He serves as a general co-chair of SPIE Industrial Optical Systems and Devices (iODS). He received B.S. in Physics from Kyoto University in Japan and M.S. and Ph.D. in Electrical Engineering from Stanford University.
