实验介绍_迈克尔逊（An introduction to the experiment） The adjustment and use of Michelson interferometer Description: Reading this information should have the basic knowledge of the theory of interference. If you have studied this subject before, it is recommended to review it in advance. If you never learn It is suggested that the relevant part of the university physics textbook should be previewed in advance. With some basic knowledge, the experiment will be more effective. 2. The first part of this information is basically the same as the corresponding part of the textbook university physics experiment which is written by the university. If you have read the textbook, you can jump This part of the material begins with thinking before the experiment. After the data is made, the section is different from the textbook, the experimental course is based on the data, so we hope that the students will read this section carefully and enter into it Before the lab, get ready for work. The Michelson interferometer is A two-beam interference by American physicist a. Michelson for the study of the speed of light in 1881 Instruments, this interferometer has made great contributions to the development of physics. The various interferometer instruments developed based on its principle are widely used in physics In the field of measurement and measurement. I. experimental purpose 1. Understand the structure principle and regulation of Michelson interferometer. 2. Master a method to measure the wavelength of laser. 3. Observe non-localized interference, localized interference and white light interference. 2. Experimental principle 1. The non-localized interference fringes generated by point light source Spherical waves emanating from two coherent point sources can cause interference in the space of encounter, and can be received at any position in this space The striations are known as non - localized interference fringes. The following analysis shows the interference fields formed by the
