一、前言全息光照相是六十年代发展起来的一种技术,是激光重要应用的一个方面。这种照相技术有很多独特的优点,因此近年来被广泛的应用于各技术领域中,用激光全息照相作无损检验的手段,是全息照相重要应用方面之一。目前,美国、日本、西德等国家已经把激光全息照相技术应用到金属部件,蜂窝结构,橡胶轮胎等生产检验中去。近几年来国内的很多单位也广泛地开展了这方面的科学研究;如北京303所、621所、沈阳112厂、桂林曙光橡胶研究所、山东化工学院、郑州工学院等单位。目前,这些单位都取得了一定的成果。
I. Preface Holographic photographic imaging is a technique developed in the 1960s and is an aspect of laser important applications. This photographic technique has many unique advantages. Therefore, it has been widely used in various fields of technology in recent years and one of the important applications of holography is to use laser hologram for non-destructive inspection. At present, the United States, Japan, West Germany and other countries have applied laser holographic technology to metal parts, honeycomb structures, rubber tires and other production tests. In recent years, many domestic units have also carried out extensive scientific research in this area; for example, Beijing 303, 621, Shenyang 112, Guilin Shuguang Rubber Institute, Shandong Institute of Chemical Technology, Zhengzhou Institute of Technology and other units. At present, these units have achieved some results.
