Full-range optical imaging of planar collagen fiber orientation using polarized light microscopy
Michaela Turčanová, Martin Hrtoň, Petr Dvořák +5
A novel method for automated assessment of directions of collagen fibers in soft tissues is presented. It is based on multiple rotated images obtained via polarized light microscop…
Optically tunable Mie-resonance VO2 nanoantennas for metasurfaces in the visible
Peter Kepič, Filip Ligmajer, Martin Hrtoň +4
Metasurfaces are ultrathin nanostructured surfaces that can allow arbitrary manipulation of light. Implementing dynamic tunability into their design could allow the optical functio…
Single-Shot Orientation Imaging of Nanorods Using Spin-to-Orbital Angular Momentum Conversion of Light
Tomáš Fordey, Petr Bouchal, Michal Baránek +7
The key information about any nanoscale system are orientations and conformations of its parts. Unfortunately, these details are often hidden below the diffraction limit and elabor…
Plasmonic antennas with electric, magnetic, and electromagnetic hot spots based on Babinet's principle
Martin Hrtoň, Andrea Konečná, Michal Horák +2
We theoretically study plasmonic antennas featuring areas of extremely concentrated electric or magnetic field, known as hot spots. We combine two types of electric-magnetic comple…
Geometric-phase microscopy for high-resolution quantitative phase imaging of plasmonic metasurfaces with sensitivity down to a single nanoantenna
Petr Bouchal, Petr Dvořák, Jiří Babocký +8
Optical metasurfaces have emerged as a new generation of building blocks for multi-functional optics. Design and realization of metasurface elements place ever-increasing demands o…
