Abstract
The holographic interferometry is more and more used in industry as a nondestructive testing method. It is competing with conventional testing methods, which are limited in use, especially when dealing with composites and reinforced materials. One has to refuse the opinion, that the application of holographic interferometry demands specially qualified personnel with long-time training. Press button-apparatus are proving, that serial testing can be performed by semiskilled operators even today. The examples, presented in the following text, are mainly suitable for three important fields of application: 1. The best known application of holographic interferometry is the nondestructive testing. For some tasks testing automata are constructed, that only for operation and interpretation of the interferogram need semiskilled operators. The examples shown here mainly relate to adhesive joints and reinforced plastics. 2. An important field of application of holographic interferometry is the optimization during the construction process, which is done to a great extent in the development laboratories of great companies. 3. Another wide field of application is the vibration analysis as a tool for noise reduction at motor vehicles and machines or for (preventive) damage analysis at turbine blades.
