Michelson interferometer

(mÿ -kĕl-sŏn) An early form of interferometer in which a beam of light is split and subsequently recombined. Any difference in optical path traveled by the two beams leads to a phase difference between the recombining beams, and hence interference fringes are produced.

(optics)
An interferometer in which light strikes a partially reflecting plate at an angle of 45°, the light beams reflected and transmitted by the plate are both reflected back to the plate by mirrors, and the beams are recombined at the plate, interfering constructively or destructively depending on the distances from the plate to the two mirrors.

The technique replaces the laser cavity end mirror with a volume Bragg grating (VBG) and Michelson interferometer to select lasing at one of the cavity longitudinal eigenmodes whilst suppressing others.
The measurement setup used optical fiber Michelson interferometer and sophisticated signal processing to extract the useful data, where the used optical fiber was spirally twisted and built in a bed mattress.
In the case of grating-based MSF sensors, Bragg gratings (FBGs) [15] and long-period gratings (LPGs) [16] are inscribed along the MSF; meanwhile, for interferometric geometries, different configurations can be used such as the Mach-Zehnder interferometer [17], Sagnac interferometer (SI) [18], Fabry-Perot interferometer [19], or Michelson interferometer [20].

Using SR, a Michelson interferometer should not reveal any fringe shifts on rotation.
TD-OCT was the first to be developed and its working principle is quite similar to a Michelson interferometer [5].
introduced the concept of stream cipher to encode the secret images into two POMs based on Michelson interferometer, in which one POM is served as the encryption key while the other regarded as the ciphertext [23]; Yuan et al.
In this paper, we propose polarization interferometric nonlinear optical confocal microscope, which is a confocal microscope having high three-dimensional resolution even with continuous wave (CW) laser, incorporating a polarization Michelson interferometer. As with Raman microscope and CARS microscope, the microscope proposed observes the dielectric medium under the diffraction limit without fluorescent probes [6].
