Dispersion effects in fiber optic interferometry

Optical Engineering, 1997
An 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

Dispersion at nuclear resonance in time-delayed interferometry

Physical Review B, 1994
Interference between x-ray beams scattered from a nuclear resonance in stainless-steel foils of different thicknesses has been observed. In-phase and out-of-phase oscillations have been measured for yields with three different time windows, which exist because of a sign change of the amplitude describing the time evolution of the nuclear-resonant ...

Enhanced spectral resolution via externally dispersed interferometry

SPIE Proceedings, 2012
Externally dispersed interferometry (EDI) uses a hybrid spectrometer that combines a Michelson interferometer in series with a grating spectrometer. EDI provides a means of deriving spectral information at a resolution substantially higher than that provided by the grating spectrograph alone.

Chirped-pulse interferometry for dispersion-cancelled OCT

2011 Conference on Lasers and Electro-Optics Europe and 12th European Quantum Electronics Conference (CLEO EUROPE/EQEC), 2011
Optical coherence tomography (OCT) is a non-invasive imaging technology based on low-coherence interferometry that is rapidly finding novel applications in biological sciences and medicine, particularly in disease detection, since it allows high-resolution depth profiles of the samples under consideration [1].

Longitudinal coherence and interferometry in dispersive media

Physical Review A, 1983
For 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.

Dispersion measurements of water with spectral interferometry

Chinese Optics Letters, 2009
The spectral relative phase is directly derived from the spectrally resolved interferogram by the Fourier transform method. Furthermore, the spectral absolute phase can also be found. The spectral absolute phase is used to measure the refractive index.

Bandwidth limitations and dispersion in optical stellar interferometry

Applied Optics, 1996
The fringe visibility measured by a stellar interferometer may be degraded if the interferometer uses an air delay line without compensating for longitudinal dispersion. Whereas in such circumstances simultaneous observations across the visible spectrum are shown to be impracticable at baselines as short as 10 m, it is shown possible to detect 95% of ...

Dispersion Cancellation and Manipulation in Quantum Interferometry

Frontiers in Optics 2008/Laser Science XXIV/Plasmonics and Metamaterials/Optical Fabrication and Testing, 2008
We demonstrate simultaneous even- and odd-order spectral dispersion cancellation in a single experiment. We also present a spatial counterpart of the dispersion cancellation effect that leads to the removal of even-order aberrations in quantum interference.
