Abstract
To the present time photorefractive (PRC) crystals have found wide application at creation interferometers devices. It is caused by presence in photorefractive environments of nonlinear optical effects. One of such effects is the effect polarization self-modulation One-fiber few-modes interferometers are used for creation of sensors of physical sizes, but there is a problem of processing of their output signals. In this report, I review the method of processing of output signal with the help of the effect polarization self-modulation in PRC for one-fiber few-mode interferometer (in which propagate only 2 or 3 modes). The submitted method in comparison with existing methods has the following advantages: the linear transfer characteristic and signal is formed on the first harmonic. The installation is assembled, with which help the idea of processing of an output registered signal in one-fiber few-modes interferometer was embodied. Besides as addition, the application photorefractive crystals opens an opportunity of giving to measuring system an ability to adapt under at slow changes of an environment, for example, slow temperature changes.
