Enhancing film measurement accuracy with calibration and correction techniques for a line-field Linnik white-light dispersive interferometer

Optical Engineering: The Journal of SPIE
. White-light dispersive interferometry (WLDI) is an optical metrology technique that is used to measure precise and complex surfaces. However, the accuracy of spectral signal acquisition can affect the precision and subsequent evaluation of measurement ...

Controlling visibility in nonlinear interferometry for spectroscopy with undetected photons

APL Photonics
Quantum nonlinear interferometers play an important role in quantum imaging and sensing applications. Here, we demonstrate the tailoring of the frequency-angular spectrum of such a device, where we use a linear dispersive medium as a phase corrector.

Two-wavelength dispersion holographic lateral-shift interferometry

Technical Physics, 2004
It is demonstrated that two-wavelength holographic interferometry with a small lateral shift in a grating interferometer makes it possible to study the dispersion characteristics of transparent objects using probe beams with arbitrary wavelengths. Interference patterns reconstructed represent fringes on the reconstructed image of the object, which ...
