Optimization of the Characteristics of Fiber-Optic Fabry–Perot Interferometer Mirrors in Measurement Systems Using Broadband Radiation
The fiber-optic Fabry–Perot interferometer (FPI) has been analyzed to determine its reflection and transmission coefficients providing the maximum useful signal in a high-precision scheme for measuring the FPI length. It is shown that the traditionally applied criterion, which is aimed at achieving the maximum visibility of the interference pattern, is not applicable in this scheme. An adequate criterion is proposed, and an analysis based on it is presented. The optimal characteristics of the FPI mirrors are calculated taking into account the diffraction effects. The result of the study is a set of simple analytical relations necessary for designing mirrors in the form of thin films deposited on the fiber end face. In particular, the possibility of implementing a desired mirror on the fiber end in the form of a single-layer dielectric film is investigated and its characteristics are obtained.
