WebThe Michelson interferometer is a device that produces interference between two beams of light. A diagram of the apparatus is shown in Fig. 1. The basic operation of the interferometer is as follows. ... fringe shift, the mirror moves through a distance equal to half the wavelength. Nature of fringes: If the two mirrors M 1 and M 2 White light has a tiny coherence length and is difficult to use in a Michelson (or Mach–Zehnder) interferometer. Even a narrowband (or "quasi-monochromatic") spectral source requires careful attention to issues of chromatic dispersion when used to illuminate an interferometer. The two optical paths must be practically equal for all wavelengths present in the source. This requirement can be met i…

Here is a schematic diagram to show how the circular fringes are formed using the Michelson interferometer. These fringes are sometimes called fringes of equal inclination or Haidinger fringes. The light comes from an extended source and is reflected off two "parallel" mirrors M 1 and M 2 as shown in figure 1 of your source.

WebJul 7, 2024 · What are fringes in interferometry? Instead of taking images of stars, an interferometer records the interference pattern (or interference fringes) created by combining the light from two or more telescopes. Interference fringes are created when light waves interfere constructively; the result is a pattern of alternating light and dark bands. WebTo better understand the interferometer used by Michelson and Morley, we use a simplified version of their instrument to measure the wavelength of the laser light source used. The second part of the experiment consists in measuring the index of refraction of air by counting fringe shifts in the interference pattern.

WebThe Michelson interferometer is used to measure small displacements. Translation of one of the mirrors by half a wavelength of the laser light causes a motion of the fringe pattern by one fringe. For example, on a precision micrometer, one small division corresponds to 10 μ m. The wavelength of the green laser light from a frequency-doubled ... WebApr 10, 2024 · Fringe shifts should be observed when a one-way interferometer at rest in the laboratory is rotated, if a preferred frame exists. If a two-way interferometer is used, no fringe shifts should be ...

WebApr 7, 2024 · Michelson, Mach-Zehnder and other similar interferometers that use quasi-monochromatic sources often rely on counting fringe shifts to measure and track gradual changes in the quantity of interest.
