一个可以从跨度的开发中受益的光学设计空间是折叠的光学体系结构，其中光限制在反射表面之间，并且在此手稿中，在反射界面上控制了波前。展示由1毫米厚的玻璃板制成的紧凑型光谱仪，其体积为7立方毫米。 〜1.2 nm，从760到860 nm解决了80多个光谱点。折叠的Metasystem设计可以应用于许多光学系统，例如光信号处理器，干涉仪，高光谱图像和计算光学系统，可显着降低它们的大小，增加了机械鲁棒性和整合的潜力。

An optical design space that can highly benefit from the recent developments in metasurfaces is the folded optics architecture where light is confined between reflective surfaces, and the wavefront is controlled at the reflective interfaces. In this manuscript, we introduce the concept of folded metasurface optics by demonstrating a compact spectrometer made from a 1-mm-thick glass slab with a volume of 7 cubic millimeters. The spectrometer has a resolution of ~1.2 nm, resolving more than 80 spectral points from 760 to 860 nm. The device is composed of three reflective dielectric metasurfaces, all fabricated in a single lithographic step on one side of a substrate, which simultaneously acts as the propagation space for light. The folded metasystem design can be applied to many optical systems, such as optical signal processors, interferometers, hyperspectral imagers, and computational optical systems, significantly reducing their sizes and increasing their mechanical robustness and potential for integration. Here, the authors introduce the folded metasurface optics architecture by demonstrating a compact high-resolution optical spectrometer made from a 1-mm-thick glass slab. The spectrometer has a resolution of 1.2 nm, resolving more than 80 spectral points in a 100-nm bandwidth centered at 810 nm.
