目前,随着用全息照相法记录物体图象的技术的发展,在物理系和数理系的普通物理课程中,研究全息照相原理的问题已占了相当的位置。但到目前为止,同时在很多听众面前展示重现全息图象的教学演示方法实际上还没有。我们实现了在大教室中,用比较简单的方法再现平面物体的图象,并解释全息照相的基本特性。 At present, with the development of the technology of recording object images by holography, the problem of studying holographic principles occupies a considerable place among general physics courses in physics and mathematics. So far, however, teaching demonstrations that showcase holographic images in front of many listeners have not actually been done yet. We have realized that in a large classroom, we can reproduce images of planar objects in a relatively simple way and explain the basic characteristics of holography.
