能够辐射单一频率的激光器的出现,有力地推动了基于单色光干涉现象的全息照相术的发展。而光频段全息照相术的发展又推动了它在声学和射频波段的应用。全息照相术,这是一种基于单色光场干涉现象的技术,先将三维物体的信息记录在 The emergence of lasers capable of radiating a single frequency strongly contributes to the development of holography based on monochromatic light interference phenomena. The development of optical band holography has also promoted its application in the acoustic and radio frequency bands. Holography, a technique based on the phenomenon of monochromatic light field interference, first records the information of the three-dimensional object
