US Patent Issued on Oct. 28 for "Wavefront reversal device using a MEMS spatial phase modulator integrated with a retroreflector array" (California Inventor)

ALEXANDRIA, Va., Oct. 28 -- United States Patent no. 12,454,453, issued on Oct. 28.

"Wavefront reversal device using a MEMS spatial phase modulator integrated with a retroreflector array" was invented by David M Pepper (Camarillo, Calif.).

According to the abstract* released by the U.S. Patent & Trademark Office: "Wavefront reversal device using a MEMS spatial phase modulator integrated with a retroreflector array. A cat's eye retro reflector array is integrated with a phase only MEMS spatial light modulator (SLM) so that each cat's eye retro-reflector in the array is integrated into each pixel of the MEMS SLM. The composite MEMS device provides continuous analog phase modulation and retro-reflection for each pixel. By integrating a cat's...
