Centimeter-Scale Achromatic Hybrid Metalens Design: A New Paradigm Based on Differentiable Ray Tracing in the Visible Spectrum

Autor: Zhang, Qiangbo, Yu, Zeqing, Wang, Mengguang, Liu, Yiyang, Zhang, Changwei, Wang, Chang, Zheng, Zhenrong

Single metalenses are limited by their physical constraints, precluding themselves from achieving high numerical aperture across a wide visible spectral band in large-aperture applications. A hybrid system that integrates a metalens with a refractive

Neural-Optic Co-Designed Polarization-Multiplexed Metalens for Compact Computational Spectral Imaging

Autor: Zhang, Qiangbo, Lin, Peicheng, Wang, Chang, Zhang, Yang, Yu, Zeqing, Liu, Xinyu, Xu, Ting, Zheng, Zhenrong

As the realm of spectral imaging applications extends its reach into the domains of mobile technology and augmented reality, the demands for compact yet high-fidelity systems become increasingly pronounced. Conventional methodologies, exemplified by

End-to-end joint optimization of metasurface and image processing for compact snapshot hyperspectral imaging

Autor: Zhang, Qiangbo, Yu, Zeqing, Liu, Xinyu, Wang, Chang, Zheng, Zhenrong

Traditional snapshot hyperspectral imaging systems generally require multiple refractive-optics-based elements to modulate light, resulting in bulky framework. In pursuit of a more compact form factor, a metasurface-based snapshot hyperspectral imagi
