Michelson interferometer – High Resolution

With the aid of two mirrors in a Michelson arrangement, light is brought to interference. While moving one of the mirrors, the alterationin the interference pattern is observed and the wave length of the laser light determined.

  • Learn about the measurement principle with which gravitational waves can be observed
  • Assemble your own interferometer using invidual optical components
  • Find out that even lasers have limited coherence length

  1. Construction of a Michelson interferometer using separate components.
  2. The interferometer is used to determine the wavelength of the laser light.
  3. The contrast function K is qualitatively recorded in order to determine the coherence length with it.
