Improving specificity and axial spatial resolution of refractive index imaging by exploiting uncorrelated subcellular dynamics
Herve Hugonnet, HyunJun Han, Weisun Park +1
Holotomography, a three-dimensional quantitative phase imaging technique, presents an innovative, non-invasive approach to studying biological samples by exploiting the refractive…
Single-shot refractive index slice imaging using spectrally multiplexed optical transfer function reshaping
Chungha Lee, Herve Hugonnet, Juyeon Park +3
The refractive index (RI) of cells and tissues is crucial in pathophysiology as a noninvasive and quantitative imaging contrast. Although its measurements have been demonstrated us…
Dielectric-tensor reconstruction of highly scattering birefringent samples
Herve Hugonnet, Moosung Lee, Seungwoo Shin +1
Many important microscopy samples, such as liquid crystals, biological tissue, or starches, are birefringent in nature. They scatter light differently depending on the light polari…
Regularization of dielectric tensor tomography using total variation
Herve Hugonnet, Seungwoo Shin, Yongkeun Park
Dielectric tensor tomography reconstructs the three-dimensional dielectric tensors of microscopic objects and provides information about the crystalline structure orientations and…
Non-resonant lasing in a deep-hole scattering cavity
ChulMin Oh, Ho Jin Ma, KyeoReh Lee +2
Random lasers are promising in the spectral regime, wherein conventional lasers are unavailable, with advantages of low fabrication costs and applicability of diverse gain material…
Spatially multiplexed dielectric tensor tomography
Juheon Lee, Seungwoo Shin, Herve Hugonnet +1
Dielectric tensor tomography (DTT) enables the reconstruction of three-dimensional (3D) dielectric tensors, which provides a physical measure of 3D optical anisotropy. Herein, we p…
