Interferometry is a science that deals with the interference of waves and their measurement. Of light waves, electromagnetic waves and sound waves.

Due to the interference of waves, various spatial, time and frequency-related distribution patterns are created, from which physical parameters can be derived. Thus, interferometers can be used to measure refractive indices ofoptical fibers, magnetic field strengths of electromagnetic waves, reflection points in transmission media, temperatures, pressures or strains.
