ALEXANDRIA, Va., June 16 -- United States Patent no. 12,305,989, issued on May 20, was assigned to Honeywell International Inc. (Charlotte, N.C.).
"Resonator optical gyroscope with diminished bias error" was invented by Jianfeng Wu (Tucson, Ariz.), Tiequn Qiu (Glendale, Ariz.) and Matthew Wade Puckett (Phoenix).
According to the abstract* released by the U.S. Patent & Trademark Office: "Techniques are provided for diminishing bias error, in a resonator optical gyroscope, due to an undesired, parasitic optical mode which is orthogonal to a desired optical mode. Energy levels of the undesired, parasitic mode can be diminished utilizing polarizing beam splitters each of which suppresses energy of the undesired, parasitic mode of a clockwise ...
