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 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…

Large-scale holographic particle 3D imaging with the beam propagation model
Hao Wang, Waleed Tahir, Jiabei Zhu +1
We develop a novel algorithm for large-scale holographic reconstruction of 3D particle fields. Our method is based on a multiple-scattering beam propagation method (BPM) combined w…
