Abstract

A multibeam Fabry-Perot interferometer is used for measuring very small periodic displacements (SPD). The steepness of such an interferometer as well as the high gain of the photomultiplier and the powerful laser allow one to measure SPD of the order of 10−19 m at room temperature. Analysis of all the noise factors restricting the sensitivity (heat fluctuations of the surfaces of the mirrors, shot effect, radiation pressure noise) shows that at room temperature the heat noise is the most important.
