【摘要】 提出了在位相差放大技术中用来消除波象差的一种方法。在MachZehnder干涉仪的两臂中分别插入一张全息图,其中一张既带有物体位相信息,也带有系统象差;另一张只带有系统象差信息;再现时能消象差,同时物体位相差得到放大。更多还原

【Abstract】 A method for eliminating wavefront aberration, used in phase difference amplification was proposed. Two holograms were inserted in two optical paths of a Mach-Zehnder interferometer respectively. One of the holograms recorded the information of both object phase and wave-front aberration of the system, the other recorded only that of wavefront abarration. While reconstructing, the wayefront abarratioa could be eliminated and the amplified phase difference obtained. The experimental results were given finally.更多还原
