Stroboscopic holographic interferometry: Application of digital techniques
Abstract
Stroboscopic holographic interferometry is a very powerful tool for study of vibrating objects. It is shown how its capabilities can be extended by applying digital techniques to make real-time measurements of the optical path differences at a uniformly spaced array of points covering the interference pattern. Areas vibrating in antiphase can be identified clearly, and a three-dimensional displacement map of the surface of the object can be generated.
