Michelson Interfrometer

This demonstration uses the famous Michelson interferometer which is used either for precise distance measurements or the wavelength of the laser. An assembly of optical components including HeNe laser, mirrors and converging lenses is used. The interference pattern is produced by splitting the beam into two paths using a 50:50 beam splitter. The movable mirror is motor controlled and computer interfaced, a source of changing the path length and produce a interference fringes.
