Quantitative three-dimensional absorption imaging in standard brightfield microscopes
Yoonjae Chung, Sehyun Lee, Herve Hugonnet +5
Optical absorption is a primary, label-defining contrast across biology, pathology, and materials science, yet three-dimensional quantitative absorption imaging has remained largel…
Programmable spatial coherence tomography: diffraction-limited three-dimensional reflection imaging under modulated monochromatic illumination
Herve Hugonnet, Jieun Choi, Gyoung Hwan Kim +9
Depth sectioning in reflection microscopy has predominantly relied on temporal coherence gating. Here we show that volumetric reflection tomography at diffraction-limited resolutio…
Video-rate holographic telepresence via single-shot, reference-free wavefront measurement
Minwook Kim, Chansuk Park, Chulmin Oh +3
We present a reference-free holographic telepresence system that directly captures and replays complex optical wavefronts from a single intensity speckle measurement. Using a pre-c…
Pupil Phase Series: A Fast, Accurate, and Energy-Conserving Model for Forward and Inverse Light Scattering in Thick Biological Samples
Herve Hugonnet, Chulmin Oh, Juyeon Park +1
We present the pupil phase series (PPS), a fast and accurate forward scattering algorithm for simulating and inverting multiple light scattering in large biological samples. PPS ac…
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…
