        "http://www.w3.org/2000/01/rdf-schema#comment" : [ "A common path interferometer is class of interferometer in which the reference beam and sample beams travel along the same path. Examples include the Sagnac interferometer, the point diffraction interferometer, and the Zernike phase contrast interferometer. A common path interferometer is generally more resilient to environmental vibrations than a \"double path interferometer\" such as the Michelson interferometer or the Mach-Zehnder interferometer." ] ,
