Mid-Infrared Photothermal Relaxation Intensity Diffraction Tomography for Video-rate Volumetric Chemical Imaging
Danchen Jia, Dashan Dong, Tongyu Li +5
Three-dimensional molecular imaging of living cells is essential for unraveling cellular metabolism and response to therapies. However, existing volumetric methods, including fluor…
Dual-wavelength Fourier Ptychographic Topography
Yi Shen, Tongyu Li, Hao Wang +7
We introduce a dual-wavelength Fourier ptychographic topography (FPT) method that extends the lambda/2 height-range limit of single-wavelength FPT. By reconstructing complex fields…
Transfer-Function Approach to Substrate-Enhanced Diffraction Tomography
Tongyu Li, Yi Shen, Dashan Dong +4
Forward and backward scattering provide complementary volumetric and interfacial information, yet conventional three-dimensional (3D) imaging typically accesses only one. In this L…
Whitened Score Diffusion: A Structured Prior for Imaging Inverse Problems
Jeffrey Alido, Tongyu Li, Yu Sun +1
Conventional score-based diffusion models (DMs) may struggle with anisotropic Gaussian diffusion processes due to the required inversion of covariance matrices in the denoising sco…
Reflection-mode Multi-slice Fourier Ptychographic Tomography
Jiabei Zhu, Tongyu Li, Hao Wang +3
Diffraction tomography (DT) has been widely explored in transmission-mode configurations, enabling high-resolution, label-free 3D imaging. However, industrial metrology application…
