Abstract

The recent interest in the development of high-sensitive, low frequency microphasemetry methods have been inspired as for tasks of fundamental physics, in particular, by the programs for gravitational waves measurement, as for applied physics, such as creation of high sensitive interferometric sensors for a number of physical values-acoustic, magnetic, and for displacements in atomic force microscopes. The present work provides a comparative analysis of the influence of quantum (shot) noise on the limit sensitivity (signal-to-noise ratio) in microphasemetry in the common regime of operation, in the steep region, and at the minimum of an interferogram with modulation of phase difference for a number of interferometric schemes. In this work, we consider the standard Michelson interferometer, Fabry-Perot cavity, and a more complex system, in which Febry-Perot cavities appear as Michelson arms. To show the results in more convenient form, we put it into the table.
