ABSTRACT:
Temperature compensation of an optical fiber interferometer is achieved by wrapping and bonding one fiber arm transversely about the length of a magnetostrictive rod which is sensitive only to the magnetic field component along its length. The other fiber arm is wrapped and bonded about two generally semicircular caps, attached to either end of the rod, in a direction along the longitudinal axis of the rod.
