 An amplitude splitting interferometer uses a partial reflector to divide the amplitude of the incident wave into separate beams which are separated and recombined . Fig . 6 illustrates the Fizeau , Mach – Zehnder and Fabry – Pérot interferometers . Other examples of amplitude splitting interferometer include the Michelson , Twyman – Green , Laser Unequal Path , and Linnik interferometer .
