ALEXANDRIA, Va., June 16 -- United States Patent no. 12,656,105, issued on June 16, was assigned to The Shape Sensing Co. (Austin, Texas).

"Birefringence mitigation in an optical network" was invented by Alex Tongue (Dripping Springs, Texas) and Justin Braun (Austin, Texas).

According to the abstract* released by the U.S. Patent & Trademark Office: "Birefringence in optical fibers is mitigated using optical frequency domain reflectometry (OFDR) having a coupling point optically connected to a reference arm with a first, single mode fiber segment and optically connected to a measurement arm having single mode optical segments and polarization maintaining optical segments. The measurement arm has a first optical circulator connected to the ...
