Optical fiber gyro
 An optical fiber gyro system provides a pair of separated optical paths containing partial common portions. A phase difference .DELTA..theta. is detected using a plurality of detectors which yield sin and cos functions in .DELTA..theta.. Functions are formed as linear couplings of these functions, and the phase difference .DELTA..theta. is obtained using the function of best sensitivity for the given range of .DELTA..theta..
