ALEXANDRIA, Va., Feb. 11 -- United States Patent no. 12,546,660, issued on Feb. 10, was assigned to Washington University (St. Louis).

"Optical whispering gallery mode barcodes for high-precision and wide-range measurements" was invented by Lan Yang (St. Louis) and Jie Liao (St. Louis).

According to the abstract* released by the U.S. Patent & Trademark Office: "Systems and methods for measuring a temperature using an optical whispering gallery mode (WGM) resonator are disclosed. The system includes a WGM resonator operatively coupled to a tunable laser source and a detector, as well as a computing device. The computing device is configured to transform a transmission spectrum from the detector into a measured barcode that includes a matri...
