Investigation of Holographic Testing Techniques

Abstract

The final technical report on holographic testing research includes a number of specific investigations conducted at the Radar and Optics Division of Willow Run Laboratories and at Cooley Electronics Laboratory of The University of Michigan. The investigations described include the following: (1) interferometric detection of microcracks; (2) detection of debonds in honeycomb sandwich structures, (3) real-time monitoring of stress-corrosion cracking, (4) interferometry of three-dimensional, refractive-index fields, (5) measurement of vibrational amplitudes, (6) holographic contouring, (7) optical determination of rms surface roughness, and (8) non-destructive inspection of shell casings and projectiles. The report also includes a brief introductory section on holography and holographic interferometry and a brief glossary of technical terms for the benefit of readers who are not acquainted with this technique.
