Optical Interference for Deformation Measurements--Classical, Holographic and Moiré Interferometry
Chapter
Abstract
Interferometry is a powerful tool. It enables measurements of surface topography, dimensional changes and deformations of solid bodies, all in the sub-wavelength sensitivity range. This article is a tutorial treatment of the subject. Its purpose is to introduce modern interferometric techniques of engineering measurements; and to explain them in sufficient detail to generate a comfortable association with the subject. Ultimately, the mission is to foster understanding and appreciation in order to inspire increased utilization and further development.
