Author: Frejlich J.

Abstract: We describe the latest improvements in holographic interferometry that enable the realtime 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.
