"WebThe significance of the birefringence is that optical materials can be cut to impose specific changes in the polarization of incident beams. For example half-wave plates are cut to impose 180o (1 2 2! ()) phase shifts. When linearly polarized light travels in a birefringent crystal, the phase difference imposed on the two " - Birefringence material

Stress in optical materials commonly presents itself by generating an anisotropy in the material ( Stress-Induced birefringence ). Measuring the birefringence, material thickness, and knowing the material's stress optic coefficient, allows the calculation of the resulting differential stress in the material.
