Autoanalysis system for stroboscopic holographic interferometry

Xiwen Wang, Ming Kang

Open publisher page 0 citations

Abstract

In this paper, an analysis theory of real-time stroboscopic holographic interferometry with fringe drift counting technique is discussed. Based on the theory, a real-time auto- analysis system for stroboscopic interferometry is researched. The system can be used to analyzing object's vibration. The difficulty of identifying the node-locus in stroboscopic interference pattern is disposed. And the influence of primitive fringe on the quantitative analysis of the real-time holography is also eliminated.
