Abstract
Method comprises (1) introducing a polarized light beam into the convex surface of an optically-transparent body whereby the beam propagates in the body in a guided manner near the surface, (2) extracting at least a portion of the beam from the body through the surface at a distance from where the beam was introduced, (3) sensing the change in polarization state of the extracted portion of the beam occurring during its propagation in the body, and (4) calculating the value of stress from the sensed change in polarization state.
