Stabilized fiber-optic Mach–Zehnder interferometer for carrier-frequency rejection
, 2013 We have demonstrated stabilization of a fiber-optic Mach–Zehnder interferometer, with a centimeter-scale path difference, to the transmission minimum for the carrier wave of a frequency-modulated laser beam.

Optimization of a field-widened Michelson interferometer [PDF]
, 1985 This paper considers the optical design of a wide-angle fixed-path Michelson interferometer consisting of two arm glasses and an air gap. It is shown that this configuration can be optimized to give (a) extra large fringes (over 50° in diameter) over a

WAMDII: wide-angle Michelson Doppler imaging interferometer for Spacelab [PDF]
, 1985 A wide-angle Michelson Doppler imaging interferometer (WAMDII) is described that is intended to measure upper atmospheric winds and temperatures from naturally occurring visible region emissions, using Spacelab as a platform.

Physical Review Letters, 1991 We have demonstrated an interferometer for atoms. A three-grating geometry is used, in which the interfering beams are distinctly separated in both position and momentum. We used a highly collimated beam of sodium atoms with a de Broglie wavelength of 16 pm and high-quality 0.4-\ensuremath{\mu}m-period free-standing gratings which we fabricated using a

A membrane interferometer [PDF]
Proceedings of the National Academy of Sciences, 2009 Freestanding phospholipid bilayers have been assembled spanning shallow, micrometer-sized wells etched into a Si wafer substrate so that the bilayers are near (within hundreds of nanometers) but not in contact with the wafer surface. The proximity of the bilayers to the highly reflective Si/SiO 2

IEEE Access, 2021 A strong signal through the antenna sidelobes can be interpreted as a main lobe signal and may cause a major angle error in the direction finding system. An auxiliary antenna channel in the Maisel’s sidelobe blanking system increases the cost, and

Piezoelectric effects of single-crystal GaAs and multi-layered AlxGa1-xAs/GaAs material measured by the Michelson interferometer [PDF]
Songklanakarin Journal of Science and Technology (SJST), 2003 The inverse piezoelectric effect, in which the strains were electrically induced, in a single crystal of GaAs and in a multilayer structure of AlxGa1-xAs/GaAs was measured using a simple optical system, i.e., Michelson interferometer.
