Deep-ultraviolet ptychographic pocket-scope (DART): mesoscale lensless molecular imaging with label-free spectroscopic contrast
Ruihai Wang, Qianhao Zhao, Julia Quinn +11
The mesoscale characterization of biological specimens has traditionally required compromises between resolution, field-of-view, depth-of-field, and molecular specificity, with mos…
Ptycho-endoscopy on a lensless ultrathin fiber bundle tip
Pengming Song, Ruihai Wang, Lars Loetgering +8
Synthetic aperture radar (SAR) utilizes an aircraft-carried antenna to emit electromagnetic pulses and detect the returning echoes. As the aircraft travels across a designated area…
Spatially-coded Fourier ptychography: flexible and detachable coded thin films for quantitative phase imaging with uniform phase transfer characteristics
Ruihai Wang, Liming Yang, Yujin Lee +8
Fourier ptychography (FP) is an enabling imaging technique that produces high-resolution complex-valued images with extended field coverages. However, when FP images a phase object…
Lensless polarimetric coded ptychography for high-resolution, high-throughput gigapixel birefringence imaging on a chip
Liming Yang, Ruihai Wang, Qianhao Zhao +7
Polarimetric imaging provides valuable insights into the polarization state of light interacting with a sample. It can infer crucial birefringence properties of bio-specimens witho…
Lensless coherent diffraction imaging based on spatial light modulator with unknown modulation curve
Hao Sha, Chao He, Shaowei Jiang +6
Lensless imaging is a popular research field for the advantages of small size, wide field-of-view and low aberration in recent years. However, some traditional lensless imaging met…
Bypassing the resolution limit of diffractive zone plate optics via rotational Fourier ptychography
Chengfei Guo, Shaowei Jiang, Pengming Song +4
Diffractive zone plate optics uses a thin micro-structure pattern to alter the propagation direction of the incoming light wave. It has found important applications in extreme-wave…
