US Patent Issued to Honeywell Aerospace US on Oct. 27 for "Resonant optical gyroscope using optical frequency combs each of whose spectral components are not phase locked" (Arizona, Minnesota Inventors)

ALEXANDRIA, Va., Oct. 27 -- United States Patent no. 12,774,887, issued on Oct. 27, was assigned to Honeywell Aerospace US LLC (Phoenix).

"Resonant optical gyroscope using optical frequency combs each of whose spectral components are not phase locked" was invented by Jianfeng Wu (Tucson, Ariz.), Tiequn Qiu (Glendale, Ariz.), Steven Tin (Edina, Minn.) and Glen A. Sanders (Scottsdale, Ariz.).

According to the abstract* released by the U.S. Patent & Trademark Office: "A technique is provided for reducing angle random walk (ARW) noise in a resonant optical gyroscope (ROG) using a pair of optical frequency combs. The ARW noise is reduced by propagating each optical frequency comb through a dispersive optical component. As a result, at least so...
