Abstract:

A fiber interferometer gyro employing a continuous, integral looped single-mode fiber is coupled ot bidirectionally transmit clockwise and counterclockwise pulsed beams of light through a coiled continuous integral single-mode fiber from a laser to a pair of detectors. A suitably polarized piezoelectric cylinder is fitted about a portion of the continuous integral single-mode fiber to change the refractive index of that portion of the continuous integral single-mode fiber when appropriate electric fields are impressed across it. Changing the refractive index in only that portion of the continuous integral single-mode fiber results a selective phase biasing between the clockwise and counterclockwise traveling pulsed beams so that a rotation displacement of the interferometer gyro is more easily detected.
