One "fringe shift" corresponds to a change in "arm length", ∆∆∆∆L1, equal to λλλ/2 . You get ∆∆∆∆L1 by taking the difference between two-micrometer readings. The goal in this lab, as in all ... Weba Michelson interferometer in gas-mode can detect ab-solute motion, as we now see. So as better and better vacuum interferometers were developed over the last 70 years the rotation-induced fringe shift signature of ab-solute motion became smaller and smaller. But what went unnoticed until 2002 was that the gas in the in-

Michelson interferometer fringe shift

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… Webjustify uncertainty, and use the rotational mount to position the sample in one arm of your interferometer.
