In collaboration with UC Berkeley, we designed a phase modulation MEMS for optical beam steering. This new type of MEMS is fast and efficient, and can be useful for LIDAR or optical switch for data center.
05/19/2019: I will be attending the OSA Digital Holography Conference in Bordeaux, France. Link
I will be presenting the following 4 papers:
- M3A.1. Holographic See-Through Displays. (Invited)
- M5A.2. Tabletop Radar Range Using Interferometric Time-of-Flight.
- W4A.2. Continuous Recording of Holographic Stereograms.
- Th3A.24. Holographic Angular Amplification for LIDAR Scanner.
I will also be panelist for the OSA holography technical group event: “The next scientific contributions of Holography”, taking place Monday May 20th during lunch time.
04/11/2019: P.-A. Blanche and B. Lynn: “Diffraction-Based light beam scanner” Patent US 2019/0107711 A1. Link
This patent is about how to use a spatial light modulator to steer a light beam and compensate for the chromatic aberration in a monostatic LIDAR configuration.
