Abstract
REAL-TIME HOLOGRAPHIC INTERFEROMETRY CAN BE USED TO DETERMINE THE DISPLACEMENT AND DEFORMATION OF AN OBJECT WHICH HAS BEEN STRESSED. PHASE-MEASURING TECHNIQUES CAN AND HAVE BEEN ADDED TO PROVIDE QUANTITATIVE INFORMATION ABOUT THE DEFORMATION OF THE OBJECT IN ONE PARTICULAR DIRECTION. IN ORDER TO DETERMINE THE STRAIN IN THE TEST OBJECT, THREE OR FOUR SEPARATE MEASUREMENTS ARE NECESSARY SO THAT THE THREE-DIMENSIONAL VECTOR DISPLACEMENT OF THE OBJECT CAN BE DETERMINED. THIS WORK WILL DETERMINE WHAT MEASUREMENTS AND CALCULATIONS ARE NECESSARY TO QUANTITATIVELY DETERMINE VECTOR DISPLACEMENT AND STRAIN OF THE OBJECT UNDER TEST, AS WELL AS WHAT SOFTWARE IS NECESSARY TO DEVELOP FOR USE BY MECHANICAL ENGINEERS STUDYING OBJECT DEFECTS. THE ULTIMATE OBJECTIVE OF THIS WORK IS TO PRODUCE A COMPLETE TESTING SYSTEM CONTROLLED BY A DESKTOP COMPUTER TO ACQUIRE AND ANALYZE HOLOGRAPHIC INTERFEROMETRY DATA.
