US Patent Issued to Arizona Board of Regents on Behalf of the University of Arizona on June 24 for "Phase-shifting diffraction phase interferometry" (Arizona Inventors)

ALEXANDRIA, Va., June 25 -- United States Patent no. 12,339,430, issued on June 24, was assigned to Arizona Board of Regents on Behalf of the University of Arizona (Tucson, Ariz.).

"Phase-shifting diffraction phase interferometry" was invented by Rongguang Liang (Tucson, Ariz.) and Xiaobo Tian (Tucson, Ariz.).

According to the abstract* released by the U.S. Patent & Trademark Office: "Snapshot phase-shifting diffraction modules and associated systems and methods are described that enable high spatial and temporal resolution phase imaging with high immunity to environmental factors such as vibrations and temperature changes. One example optical diffraction phase module includes a polarization grating to produce two circularly polarized lig...
