Title: Advances in real-time holographic interferometry for the measurement of vibrations and deformations
Author: Frejlich, J
Garcia, PM
Abstract: We describe the latest improvements in holographic interferometry that enable the real-time measurement of vibrational modes and static deformations in surfaces using low-power laser illumination and a photorefractive Bi12TiO20 crystal as the recording medium. An efficient setup has been developed where the most critical elements have been optimized: target illumination and backscattered light collection, distribution of light between the object and reference beams, and stabilization system operation. Experimental results for vibration and deformatiom measurement are reported. (C) 2000 Elsevier Science Ltd. All rights reserved.
