摘要：
A method for signal reconstruction in a fiber-optic sensor based on a Fabry -Perot interferometer, which uses two channels with different wavelengths that are selected such that the phase shift of the signals in these channels is pi/2, is proposed. Examples of the applicability of the method for reconstructing signals in acoustic and vibration sensors are given. A significant increase in the dynamic range of recordable displacements in such sensors is obtained using the proposed method, compared with the single-wave version.
