This contribution deals with a polariscope, an instrument for determining internal strain in a transparent medium by exploiting its polarization transmission: When a sample of birefringent material is inserted in a pola-rized beam of light a fringe pattern is observed. The pattern is captured by a camera and processed to reveal internal stresses in the probe. However, in order to completely specify stresses, four patterns obtained under different optical conditions are used. These can bedoi:10.1109/radioelek.2011.5936481 fatcat:pwl3fp5ejjbnhea6k3zem5f7uy
