Geometric-Phase Microscopy for Quantitative Phase Imaging of Isotropic, Birefringent and Space-Variant Polarization Samples
Bouchal, Petr; Štrbková, Lenka; Dostál, Zbyněk; Chmelík, Radim; Bouchal, Zdeněk (Springer Nature, 2019-03-05)We present geometric-phase microscopy allowing a multipurpose quantitative phase imaging in which the ground-truth phase is restored by quantifying the phase retardance. The method uses broadband spatially incoherent light ... -
High-Resolution Quantitative Phase Imaging of Plasmonic Metasurfaces with Sensitivity down to a Single Nanoantenna
Bouchal, Petr; Dvořák, Petr; Babocký, Jiří; Bouchal, Zdeněk; Ligmajer, Filip; Hrtoň, Martin; Křápek, Vlastimil; Faßbender, Alexander; Linden, Stefan; Chmelík, Radim; Šikola, Tomáš (American Chemical Society, 2019-01-02)Optical metasurfaces have emerged as a new generation of building blocks for multifunctional optics. Design and realization of metasurface elements place everincreasing demands on accurate assessment of phase alterations ... -
Phase of white light and its compatibility to the optical path
Bouchal, Petr; Chmelík, Radim; Bouchal, Zdeněk (Optical Society of America, 2021-03-12)The phase of monochromatic light directly relates to the optical path difference (OPD), but finding this connection for spectrally broadband light is challenging. Due to a missing concept of the compatibility between the ... -
Single-Shot Three-Dimensional Orientation Imaging of Nanorods Using Spin to Orbital Angular Momentum Conversion
Fordey, Tomáš; Bouchal, Petr; Schovánek, Petr; Baránek, Michal; Bouchal, Zdeněk; Dvořák, Petr; Hrtoň, Martin; Rovenská, Katarína; Ligmajer, Filip; Chmelík, Radim; Šikola, Tomáš (American Chemical Society, 2021-08-25)The key information about any nanoscale system relates to the orientations and conformations of its parts. Unfortunately, these details are often hidden below the diffraction limit, and elaborate techniques must be used ...
