Fringe patterns for axial, radial and angular incidences can be analyzed later for extracting the photoelastic unknowns and hence individual stress components. Axisymmetric specimens can thus be analyzed nondestructively in a whole-field manner. The quality of optical data acquisition with this system is consistently high due to high levels of scattered light intensity. This method is particularly attractive because even a low power laser is sufficient for data acquisition. Though we have demonstrated fringes using a stress-locked specimen, live loaded specimens can also be examined provided suitable loading fixtures are built to generate high stresses in three dimensional models. High stress levels are necessary to induce sufficient fringes for recording.
