Reference-Beam-Assisted Perturbation-Resistant Imaging Through A Single Multimode Fiber
Bowen Sun, Maohan Li, Jingwei Luo +7
Multimode fiber (MMF) imaging is highly sensitive to mechanical perturbations, which alter modal coupling and disrupt the speckle-to-target mapping. Here, we propose a reference-be…
Scattering-force-driven light-sheet fluorescence microscopy for scan-free three-dimensional imaging
Sen Geng, Zhuoren Wan, Zhaoyang Wen +6
Optical manipulation offers a powerful non-contact approach to precise positioning, directional transport and three-dimensional (3D) imaging of microscale objects. However, positio…
Comb-enabled spectral-domain image transport through perturbation-prone multimode fibers
Maohan Li, Zijian Wang, Bowen Sun +9
Multimode fibers (MMFs) offer a compact platform for imaging, sensing, and information transport, but their practical deployment is hindered by sensitivity to fiber perturbations,…
High-speed hyperspectral 3D ghost imaging LiDAR
Jing Hu, Wending Huang, Tianjian Lv +7
Light detection and ranging (LiDAR) is widely used in autonomous systems and industrial metrology; however, the simultaneous acquisition of three-dimensional (3D) structure and bro…
Dual-comb correlation spectroscopy reveals laser dynamics
Xiuxiu Zhang, Zhuoren Wan, Yuling Sheng +6
Laser dynamics underpin a broad range of modern photonic technologies and continue to reveal rich nonlinear behaviors. However, existing spectroscopic tools, most notably time-stre…
Reconstructive comb spectroscopy: A single-pixel detection paradigm beyond dual-comb limitations
Dongxu Zhu, Zhuoren Wan, Xiaoshuai Ma +13
Frequency comb spectroscopy has revolutionized broadband molecular fingerprinting with mode-defined resolution. While dual-comb spectroscopy stands as a dominant paradigm for high-…
Rapid and precise distance measurement using balanced cross-correlation of a single frequency-modulated electro-optic comb
