Pdf Automatic Alignment Of A Michelson Interferometer This step by step guide covers required parts, setup instructions, and alignment tips for producing interference fringes to measure distance, wavelength, or refractive index changes in an accessible lab environment. Interferometry is a central building block for many optics measurements and a versatile tool in the laser lab. here we describe the general working principle and give a systematic and simple setup and alignment procedure.
Michelson Interfereometer The purpose of this experiment is to give you some practice in assembling, aligning and using a michelson interferometer to measure the index of refraction of air. Figure 2 shows the schematic of the michelson interferometer. the michelson interferometer is an amplitude splitting interferometer. it splits the beam into two perpendicular paths using a 50 % beam splitter. the beams then reflect from the mirrors placed on each arm and return to the beam splitter. Figure 3: leaving the laser, the beamsplitter and the moveable mirror as you nd them, adjusting the other mirror, called here the `adjustable mirror' so that the output spots overlap will bring the interferometer into alignment and produce useful optical fringes. The document provides instruction for setting up and operating a michelson interferometer. it consists of a heavy base with mirrors and a beam splitter that splits light into two paths which are then recombined to produce interference patterns.

This video shows how to set up a michelson interferometer and achieve good fringe contrast. The goal of this lab is to familiarize yourself with the michelson interferometer, to align it properly, and to measure the wavelength of the laser. the figure above shows a schematic of the michelson interferometer and a photo at the end of this guide shows an example setup. In this article, we will explore the techniques for mastering the michelson interferometer, including setting up and aligning the instrument, optimizing its performance, and advanced applications. An example of a frequently occurring problem in this experiment is the alignment of the sodium light through the interferometer. finding the right alignment is a technically demanding exercise that usually takes quite a lot of time.
