Range Determination and Evaluation of Laser Speckle Interferometry.

Abstract

The objective of the effort was to determine the range of laser speckle interferometry. An XP-250 epoxy E-glass specimen was illuminated by an optical process utilizing an argon laser as a coherent light source. The displacement was achieved by angular rotation about a reference point. Geometric and trigonometric functions were used to analytically determine magnitudes and directions of displacement. The optical setups and a description of the computer system to analyze the interferogram is also presented. An analytical-experimental comparison of displacements and rotation angle is also included. A statistical analysis including standard deviation and coefficient of variation was utilized. (Author)
