摘要
介绍了在全息平台上构建迈克尔逊干涉光路,通过干涉图像来显示微小形变,采用Pasco750数据采集器、光传感器来进行数据采集.通过新的实验方法,测量在不同振动下全息平台的固有频率.其原理简单,操作方便,精度高.
Describes the holographic platform built on the optical path of Michelson Interferometer and to display small deformation through interference. Adoption of Pasco750 data collector, light sensor for data acquisition. A new methods measure of natural frequency of holographic platform in different vibration. The principle is simple, easy to operate and high accuracy.
