尽管在全息照相术的基本工作方面取得了多么重大的进展,然而,在其实际应用方面却很少有报导。而在某些领域中,都必须把任何一种应用都看作为纯理论性的,也存在另外一些领域,在这些领域中,现实性的研究已经导致出解决特殊和实际工程问题的方法。特别可靠的两个领域就是适用于定性评定部件的变形情况的全息照相干涉测量术,以及适用于测量微粒尺寸和分布情况的佛朗霍夫全息照相术。本文将给出这些技术中的每一种应用实例,并说明典型的结果。 Despite the significant progress made in the basic work of holography, however, little is reported about its practical application. In some areas, however, any one application must be regarded as purely theoretical and there are other areas in which realistic research has led to methods of solving specific and actual engineering problems. Two areas of particular reliability are holographic interferometry suitable for the qualitative assessment of the deformation of components and Fraunhofer holography for measuring particle size and distribution. This article gives examples of each of these techniques, and shows typical results.
