Paper Abstract

In this paper, we have discussed how to use a TV-computer system in holographic interferometry. With Ar+ laser as a light source, BSO crystal as a recording material, TV- computer as a detector, holographic interference pattern is automatically scanned, recorded and judged. Not only contour map is reconstructed, 3D plot is also graphed. With BSO crystal, hologram can automatically in real-time be developed. As an example we have measured the deformation of a plate under a stress by real-time holographic interferometry of 4-interferograms method. With respect to common holographic setup, TV-computer system can automatically control shifting the phase of reference beam, exposing holograms, scanning, recording and judging interferograms.
