Nonlinear differential imaging via vectorial parametric interaction
Zhuohang Wei, Kun Huang, Heping Zeng
Optical image differentiation is a key operation for edge extraction in imaging and machine vision, yet most existing implementations rely on momentum-domain filtering elements and…
Single-photon time-stretch computational ghost spectroscopy
Zhibin Zhao, Kun Huang, Ben Sun +4
Time-stretch spectroscopy is powerful for capturing transient spectral phenomena but remains fundamentally limited by detector bandwidth or timing jitter, especially under photon-s…
Mid-infrared snapshot spectral imaging via nonlinear radial dispersion
Jianan Fang, Kun Huang, Ruiyang Qin +2
Mid-infrared (MIR) spectral imaging provides chemically specific contrast through molecular vibrational fingerprints, yet snapshot acquisition remains severely limited by the lack…
High-speed mid-infrared imaging via nonlinear multiplexed detection
Ruiyang Qin, Kun Huang, Min Peng +4
