Interferometry Michelson

Michelson interferometry is dependent on normal reflection from two mirrors at right angles, and so the same foundational argument as just given can be used to show that U(l) electrodynamics does not describe Michelson interferometry self-consistently. Without loss of generality, we can write Eq. (38) as... 

In Michelson interferometry, for example, the left-hand-side of Eq. (210) becomes... 

Abstract This tutorial shows how fundamental is the role plaid by interferences in many of the physical processes involved in astrophysical signal formating and consequently instmmentation. It is obvious in interferometry. Grating spectroscopy is explained within the same framework as Young experiment, and Fabry-Perot filters are explained as Michelson interferometers.Polarization interferences, used in Lyot filters, are discussed, emphasizing the analogy with echelle gratings. 

Fourier transform (FT) IR spectroscopy is one of several nondispersive optical spectroscopies based on interferometry. A two-beam interferometer first proposed by Michelson is the basis of most modern FT-IR spectrometers, as exemplified by the schematic of the Bruker Equinox 55 spectrometer (Bruker Optik, Ettlingen, Germany) in Fig. 2. Simply described, the interferometer comprises a beam splitter and two mirrors. A collimated beam of IR energy is split at the beam splitter into equal halves. Half of the energy travels through the beam splitter to one of the mirrors, which is positioned at a fixed distance away from the beam splitter. The reflected beam travels perpendicular to the incident beam to a moving mirror. IR radiation reflects off the fixed and moving mirrors and recombines at the beam splitter. The recombined IR beam projects from the interferometer towards the detector on an optical path perpendicular to the source beam. 

Laser Interferometry. A Michelson interferometer consists of two optical path "legs which are the result of splitting the incident beam using a beamsplitter(20) a sample leg whose optical path changes as the sample length changes, and a reference leg whose optical path length is fixed. The electric field vector, E, for each leg of the interferometer can be written as ...
