Research Interests
I am interested in computational imaging with joint optimization of
optics and algorithms. I am currently working on developing computational imaging based on the metasurface for interesting
applications, such as hyperspectial imaging and differentiable framework, etc.

Laser & Photonics Reviews, 2025,
We derive the vector form of the generalized Snell’s law and develop a differentiable ray-tracing model for hybrid metalens systems. By jointly optimizing the metalens phase distribution and the aspheric parameters of the refractive lens, our hybrid metalens design achieves achromatic performance across the visible spectrum with an 8 mm aperture and a NA of 0.32.

Neural-Optic Co-Designed Polarization-Multiplexed Metalens for Compact Computational Spectral Imaging
Qiangbo Zhang†,
Peicheng Lin†, Chang Wang, Yang Zhang, Zeqing Yu, Xinyu Liu, Yanqing Lu, Ting Xu,* and Zhenrong Zheng*
Laser & Photonics Reviews, 2024,
We introduce a comprehensive end-to-end computational spectral imaging system based on a polarization multiplexed metalens. Through jointly optimizing the front-end metalens and the back-end neural network, this work achieves high-fidelity computational spectral imaging.
