Dephasing in matter-wave interferometry [PDF]

, 2005
We review different attempts to show the decoherence process in double-slit-like experiments both for charged particles (electrons) and neutral particles with permanent dipole moments.

Numerical dispersion compensation for Partial Coherence Interferometry and Optical Coherence Tomography

Optics Express, 2001
Dispersive samples introduce a wavelength dependent phase distortion to the probe beam. This leads to a noticeable loss of depth resolution in high resolution OCT using broadband light sources. The standard technique to avoid this consequence is to balance the dispersion of the sample byarrangingadispersive materialinthereference arm.

Interferometry of hyper-Rayleigh scattering by inhomogeneous thin films [PDF]

, 1999
The use of specific symmetry properties of the optical second-harmonic generation (the s,s-exclusion rule) has allowed us to observe high-contrast hyper-Rayleigh interference patterns in a completely diffuse light - an effect having no analog in case of ...
