Published in 2017 at "Inverse Problems"

DOI: 10.1088/1361-6420/aa790a

Abstract: In this paper we address the problem of estimating the phase from color images acquired with differential–interference–contrast microscopy. In particular, we consider the nonlinear and nonconvex optimization problem obtained by regularizing a least–squares–like discrepancy term… read more here.

Published in 2018 at "Journal of Microscopy"

DOI: 10.1111/jmi.12617

Abstract: Differential interference contrast‐photothermal microscopy (DIC‐PTM), as a promising tool for trace analysis of nonfluorescent compounds, suffered low sensitivity in nanospace especially for aqueous samples, due to the poor thermophysical property of water and the unoptimised… read more here.

Published in 2017 at "Journal of Biomedical Optics"

DOI: 10.1117/1.jbo.22.1.016006

Abstract: Abstract. We describe the principles of using orientation-independent differential interference contrast (OI-DIC) microscopy for mapping optical path length (OPL). Computation of the scalar two-dimensional OPL map is based on an experimentally received map of the… read more here.

Published in 2021 at "Applied optics"

DOI: 10.1364/ao.442065

Abstract: We present an external portable module for transforming bright-field microscopy to differential interference contrast (DIC) microscopy and digital holographic microscopy together. The module is composed of simple optical elements, positioned between the microscope output plane… read more here.

Published in 2017 at "Applied optics"

DOI: 10.1364/ao.56.004622

Abstract: Digital holographic measurements on planar moving objects are investigated. We discuss the dependence of the interference contrast on velocity and aperture width for both diffusely and specularly reflecting objects. Using spatial phase shifting, the experimental… read more here.

Published in 2022 at "Optics letters"

DOI: 10.1364/ol.458383

Abstract: We introduce a method to extract the photoacoustic (PA) signal from a contrast reduction of the interference spectrum acquired by spectral domain optical coherence tomography (SDOCT). This all-optical detection is achieved in a noncontact manner… read more here.
