Improved Algorithms of Data Processing for Dispersive Interferometry Using a Femtosecond Laser [PDF]

open access: yesSensors, 2023
Two algorithms of data processing are proposed to shorten the unmeasurable dead-zone close to the zero-position of measurement, i.e., the minimum working distance of a dispersive interferometer using a femtosecond laser, which is a critical issue in ...

Improvement of Distance Measurement Based on Dispersive Interferometry Using Femtosecond Optical Frequency Comb [PDF]

open access: yesSensors, 2022
Since the dispersive interferometry (DPI) based on optical frequency combs (OFCs) was proposed, it has been widely used in absolute distance measurements with long-distance and high precision.

Enhanced Data-Processing Algorithms for Dispersive Interferometry Using a Femtosecond Laser [PDF]

open access: yesSensors
Dispersive interferometry based on a femtosecond laser is extensively utilized for achieving absolute distance measurements with high accuracy. However, this method cannot measure arbitrary distances without encountering a dead zone, and deviations in ...

Nonclassical Nature of Dispersion Cancellation and Nonlocal Interferometry [PDF]

open access: yesPhysical Review A, 2009
Several recent papers have shown that some forms of dispersion cancellation have classical analogs and that some aspects of nonlocal two-photon interferometry are consistent with local realistic models.

Dispersion Compensation for Atom Interferometry [PDF]

open access: yesPhysical Review Letters, 2004
A new technique for maintaining high contrast in an atom interferometer is used to measure large de Broglie wave phase shifts. Dependence of an interaction induced phase on the atoms' velocity is compensated by applying an engineered \emph{counter phase}.
