White-light quantitative phase imaging unit

open access: yesOptics Express, 2016
We introduce the white light quantitative phase imaging unit (WQPIU) as a practical realization of quantitative phase imaging (QPI) on standard microscope platforms. The WQPIU is a compact stand-alone unit which measures sample induced phase delay under white-light illumination.

A common-path digital holographic microscope with a rotatable birefringent prism for synthesizing high-quality quantitative phase images from multi-angle interferograms

open access: yesResults in Physics, 2021
We propose a simple common-path off-axis interferometric system to perform high-quality quantitative phase imaging based on a rotatable birefringent prism that is placed at the output port of a conventional transmission or reflection microscope.

Nanoscale Magnetic Imaging using Circularly Polarized High-Harmonic Radiation [PDF]

open access: yes, 2017
This work demonstrates nanoscale magnetic imaging using bright circularly polarized high-harmonic radiation. We utilize the magneto-optical contrast of worm-like magnetic domains in a Co/Pd multilayer structure, obtaining quantitative amplitude and phase

Harmonic phase-dispersion microscope with a Mach-Zehnder interferometer [PDF]

open access: yes, 2005
Harmonic phase-dispersion microscopy (PDM) is a new imaging technique in which contrast is provided by differences in refractive index at two harmonically related wavelengths. We report a new configuration of the harmonic phase-dispersion microscope in a

Spectral-domain optical coherence phase and multiphoton microscopy [PDF]

open access: yes, 2007
We describe simultaneous quantitative phase contrast and multiphoton fluorescence imaging by combined spectral-domain optical coherence phase and multiphoton microscopy. The instrument employs two light sources for efficient optical coherence microscopic

Accurate quantitative phase imaging using generalized phase contrast

open access: yesOptics Express, 2008
The generalized phase contrast (GPC) method is explored for improving the accuracy in quantitative reconstruction of two-dimensional phase distribution from images of semi-transparent objects viewed with a common-path interferometer (CPI). We propose a novel optical scheme for highly accurate determination of the object-dependent complex synthetic ...
