Paper Abstract

In this paper, vibration detection by an optical interferometer based on self-diffraction of photorefractive two-wave mixing is described. Sensitivity of this optical interferometer using Cu doped KNSBN crystal and a He-Ne laser at 632.8 nm depends on vibration amplitude and polarization angle of incident beams. Both effects of vibration amplitude and polarization angle are researched theoretically and experimentally. Each experimental result agrees well with theoretical result.
