Method and device for the increase in the long term - operational reliability of a fiber optic interferometer

摘要

In the method according to the invention to increase the long-term - operational reliability of a fiber optic interferometer (1), the noise in the output signal of the detector of the interferometer (1) to a desired value is set by by variation of the light source current of the light source (2) of the interferometer (9) and a resulting change in the light output of the detector light power is adjusted accordingly. In this manner, it is possible both the reliability of the interferometer (1) as well as its service life increase.
