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…
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…
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…
Reflection-mode diffraction tomography of multiple-scattering samples on a reflective substrate from intensity images
Tongyu Li, Jiabei Zhu, Yi Shen +1
We introduce a novel reflection-mode diffraction tomography technique that enables simultaneous recovery of forward and backward scattering information for high-resolution 3D refra…
