Non-measurable Range Elimination of Dispersive Interferometry

Photonics Global Conference, 2023
Dispersive interferometry (DPI) is a potent tool for both scientific and industrial areas as it enables high-accuracy measurement. However, the non-measurable range (NMR) and ambiguity area severely limits application scenarios and measuring range of DPI.

Multi-Color Method for the Correction of Air Refractive Index based on Dispersive interferometry of Optical Frequency Comb

Conference on Lasers and Electro-Optics, 2021
We propose a multi-color method for the self-correction of air refractive index in moist air based on spectral interference of optical frequency comb. The relative correction stability of 4.3×10-7 is achieved.

Refractometric low coherence interferometry: dispersion interferometry

SPIE Proceedings, 2005
Primarily, low-coherence interferometry yields the optical length, i. e. the product of sample length or sample depth data times the complementary sample refractive index. Each quantity, refractive index as well as sample depth can be obtained from the optical length if the complement is known.

Dispersion compensation in stellar interferometry

Applied Optics, 1996
In long-baseline stellar interferometry, spectrometers are used to disperse starlight for measuring visibility at multiple wavelengths and for fringe tracking with channeled spectra. However, neither prisms nor gratings are well suited to the observation of fringes with wide spectral bandwidths because the mapping from wave number to detector ...
