Dispersion measurements with white-light interferometry
Journal of the Optical Society of America B, 1996White-light interferograms provide a simple, accurate, and physically intuitive picture of what happens to broadband optical pulses on transmission through, or reflection from, common optical materials. Quantitative measurement of group delay are made with an accuracy of ±0.1 fs and with high spectral resolution. This measurement accuracy is applied to

Longitudinal coherence and interferometry in dispersive media
Physical Review A, 1983For the nondispersive propagation of waves in one dimension, there is no essential difference between the concepts of longitudinal and temporal coherence, and these terms are often used interchangeably. For the dispersive propagation of waves, such as electrons or neutrons in vacuo, or light in a medium, this is no longer the case.

Dispersed interferometry for infrared exoplanet velocimetry
SPIE Proceedings, 2008The TEDI (TripleSpec - Exoplanet Discovery Instrument) is the first instrument dedicated to the near infrared radial velocity search for planetary companions to low-mass stars. The TEDI uses Externally Dispersed Interferometry (EDI), a combination of interferometry and multichannel dispersive spectroscopy. We have joined a white-light interferometer

Dispersion effects in fiber optic interferometry
Optical Engineering, 1997An extended analysis of the effects of uncompensated fiber dispersion on the fringe visibility of a fiber optic interferometer is devel- oped, with particular emphasis on stellar interferometry. Both material and waveguide dispersion for single-mode, polarization-preserving fibers are considered. It is found that dispersion causes the fringe visibility

Air-dispersion measurement by second-harmonic heterodyne interferometry
Optics Letters, 2002Interferometers with long optical paths in air usually require knowledge and control of air dispersion. In addition, the measurements at several wavelengths and the dispersion properties of air allow errors caused by air turbulence to be compensated for.

Taylor Dispersion Analysis of Polysaccharides Using Backscattering Interferometry
Analytical Chemistry, 2017Taylor dispersion analysis (TDA) allows the determination of the molecular diffusion coefficient (D) or the hydrodynamic radius (Rh) of a solute from the peak broadening of a plug of solute in a laminar Poiseuille flow. The main limitation plaguing the broader applicability of TDA is the lack of a sensitive detection modality.
