ABSTRACT:
A method for increasing the long-term operational reliability of a fiber optic interferometer. Noise in a detector output signal is set to a desired value by correcting the detector light power. Detector light power is corrected by varying a light source current of a light source of the interferometer. A change in the light source power results. It is thereby possible to increase both the reliability and useful life of the interferometer.
