摘要:

光场强度、相位与偏振分布的光学成像是众多应用的基础。传统方法依赖笨重的光学组件,且需多次测量。近年来,基于超表面(MS-based)的成像策略成为解决这些挑战的可行方案,但目前这类方法大多仅能捕获三个参数中的部分信息,且仅适用于特定光场,在处理任意场分布及实现三参数成像方面存在困难。本研究提出一种基于超表面的单次光学成像方法,可同时捕获具有任意强度、相位和偏振分布的光场的全部三个参数。我们通过对多种具有任意确定分布的光场进行成像,实验验证了该方法的通用性。本研究提出的策略有望为成像、光通信等众多领域开辟新的可行路径。

英文摘要:

Optical imaging of the intensity, phase and polarization distributions of optical field is fundamental to numerous applications. Traditional methods rely on bulky optical components and require multiple measurements. Recently, metasurface-based (MS-based) imaging strategies have emerged as a promising solution to address these challenges. However, they have been primarily limited to capturing partial information of the three parameters, tailored to specific optical fields, which poses challenges when addressing with arbitrary field distributions and achieving three-parameter imaging. In this study, we introduce a MS-based approach for single-shot optical imaging that simultaneously captures all the three parameters of optical fields with arbitrary intensity, phase, and polarization distributions. We experimentally validate the versatility of our method by conducting imaging of various types of optical fields with arbitrary well-defined distributions. The strategy presented in our work is expected to open up promising avenues for diverse applications, including imaging, optical communications, and beyond.
