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…
Mid-infrared edge-enhanced imaging via angle-selective nonlinear filtering
Zhuohang Wei, Kun Huang, Jianan Fang +1
Mid-infrared reconfigurable edge-enhanced imaging is highly demanded in sensing and vision fields. Here, we propose a novel scheme for mid-infrared upconversion imaging with high t…
Mid-infrared Fourier ptychographic upconversion imaging
Tingting Zheng, Zhuohang Wei, Kun Huang +5
Frequency upconversion technique offers an appealing approach for sensitive mid-infrared (MIR) imaging at room temperature. However, the spatial resolution of the upconversion imag…
Mid-infrared nonlinear pinhole imaging
Yanan Li, Kun Huang, Jianan Fang +2
Pinhole imaging is the most primitive and simplest lensless imaging paradigm, capable of transcending the physical limitations of conventional lens optics. This modality is particu…
Wide-field mid-infrared edge-enhanced upconversion imaging
Mengyao Yu, Zhuohang Wei, Jianan Fang +5
Edge-enhanced imaging is critical for visualizing weakly absorbing and transparent objects. Extending this functionality into the mid-infrared (MIR) region enables chemical sensiti…
High-order mid-infrared nonlinear topological differentiator
Jixi Zhang, Kun Huang, Shina Liao +3
High-order edge-enhanced imaging enables precise feature localization and effective background suppression, offering a powerful tool for real-time recognition and high-contrast vis…
