Spin-dependent metalens with intensity-adjustable dual-focused vortex beams
Qun Hao, Wenli Wang, Yao Hu +3
Vortex beams with orbital angular momentum has been attracting tremendous attention due to their considerable applications ranging from optical tweezers to quantum information proc…
Optimization of retina-like illumination patterns in ghost imaging
Jie Cao, Dong Zhou, Ying-Qiang Zhang +3
Ghost imaging (GI) reconstructs images using a single-pixel or bucket detector, which has the advantages of scattering robustness, wide spectrum and beyond-visual-field imaging. Ho…
Complementary Fourier single-pixel imaging
Dong Zhou, Jie Cao, Huan Cui +3
Single-pixel imaging, with the advantages of a wide spectrum, beyond-visual-field imaging, and robustness to light scattering, has attracted increasing attention in recent years. F…
Fast digital refocusing and depth of field extended Fourier ptychography microscopy
G. Zhou, S. Zhang, C. Zheng +3
Fourier ptychography microscopy (FPM), sharing its roots with synthetic aperture technique and phase retrieval method, is a recently developed computational microscopic super-resol…
