Nondestructive 3D Quantification of the Magnitude and Extent of Indentation-Induced Densification in Glass
Sang-min Lee, Dohyeon Lee, Juheon Lee +2
Vickers hardness characterizes resistance to indentation but does not distinguish the magnitude of local densification from the volume of glass affected. Here, low-coherence holoto…
Incoherent dielectric tensor tomography for quantitative 3D measurement of biaxial anisotropy
Juheon Lee, Yeon Wook Kim, Hwanseok Chang +4
Biaxial anisotropy, arising from distinct optical responses along three principal directions, underlies the complex structure of many crystalline, polymeric, and biological materia…
Compression benchmarking of holotomography data using the OME-Zarr storage format
Dohyeon Lee, Juyeon Park, Juheon Lee +2
Holotomography (HT) is a label-free, three-dimensional imaging technique that captures refractive index distributions of biological samples at sub-micron resolution. As modern HT s…
Rytov Approximation of Vectorial Waves by Modifying Scattering Matrixes: Precise Reconstruction of Dielectric Tensor Tomography
ChulMin Oh, Herve Hugonnet, Juheon Lee +1
Analyzing 3D anisotropic materials presents significant challenges, especially when assessing 3D orientations, material distributions, and anisotropies through scattered light, due…
High-precision and low-noise dielectric tensor tomography using a micro-electromechanical system mirror
Juheon Lee, Byung Gyu Chae, Hyuneui Kim +3
Dielectric tensor tomography is an imaging technique for mapping three-dimensional distributions of dielectric properties in transparent materials. This work introduces an enhanced…
