Paper Abstract

The holographic interferometry will be starting out the next decade with an anniversary: 1990 it will be 25 years ago since Stetson und Powell first published their utilization of the new technology for vibration analysis /0/. The new testing method quickly gained interest for the use in both industry and research. Holographic inferometry was proposed for applications such as construction optimization, damage analysis and non-destructive testing. Back then, the author of this report pointed out four main application areas which are still of the most interest today /1/: - non-destructive testing of materials and parts- static and dynamic construction optimization -measuring outlines and contours -examination of transparent materials and mediums A whole range of solutions for industrial applications were found, some of which, although slightly modified, are still in use today. For example: tire testing is a recognized testing procedure, fig.1; damage analysis has been developed by SchOnebeck to a standard practice for turbines /2/; Felske and Happe used vibration analysis to study noise sources /3/ and Brown used holographic interferometry to solve problems connected with the construction of automobiles /4/. But still these advances, which were more or less the results of pioneer work, could not be considered the real practical break-through. This was due to the fact that time was technically not yet ripe for holographic interferometry. At that time almost none of the components were available or even existed which now are obvious parts of any professional set-up. CCD-cameras could not be conceived yet, large computer systems did not even have the power of a modern day home computer and the optical components which were needed were just starting to be developed. Because of these problems, holographic interferometry was more or less restricted to research labratories There slowly but constantly fundamental advances were made which later opened up the wide range of areas in which holographic interferometry can be used now.
