Abstract

In this work we show a real time holographic polariscope. The new system is based on the dynamic anisotropic diffraction properties that happen in cubic photorefractive crystals of the sillenite family. This result represents a promising technique for possible mechanical strain and stress analysis for scientific and technical applications. The observations about the performance and the behavior of the proposed system was made in diffusion only recording mechanism in the photorefractive crystal Bi₁₂TiO₂₀ illuminated by (lambda) equals 0.633 micrometers from a He-Ne laser light source.
