Abstract:

The application of real time and double exposure holographic interferometry for the testing of induced strains, and internal flaws in laser windows has been explored. Techniques for employing these procedures are discussed, and holographic interferograms of several simulated stressed states of laser windows are included. The results indicate that these methods can be valuable nondestructive tools for the examination of nonuniform stresses induced by mounting hardware, and in addition, may provide for early detection of internal flaws within the window material.
