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