Abstract

The fiber-optic Sagnac interferometer as an example of the point sensor is described in this paper. The described applications comprising a system for rotational tables' investigation, a system for measurement of vibrations with an amplitude of nanometer order of magnitude, devices for polarization parameters analysis and the rotational waves detector base on reciprocal condition of the Sagnac interferometer operation. Because the coherence phenomenon in this configuration occurs in any source of light, the polarization role in this configuration is emphasized. Basing on this approach the possibilities of practical use of the polarization influence on interference phenomenon for the mentioned above devices are mainly discussed.
