Just for a split second I was thinking no way, but in the late 1980s, we were building fiber ring gyroscopes that depended upon an outside influence (any dimensional strain) to alter the polarization of the standing wave within the fiber. That change in polarization was proportional to some out physical quantity. They surely would have laughed at this application.
Litton Industries in Los Angeles, right? They had the whole industry wrapped up. I was employed as a part time lab tech while still in college. Got into industrial and scientific laser product engineering after graduation.
