Abstract

Metasurfaces provide a promising solution for compact and lightweight binocular depth sensing. However, most existing methods either neglect the impact of imaging quality and geometric distortion on accuracy, or rely on complex post-processing for correction and refinement. Here, we propose a low-distortion binocular metalens system for depth sensing without a backend correction algorithm. A pair of polarization-independent silicon-based metalenses, designed with a 30° field of view and <0.20% maximum distortion, are monolithically integrated on a single substrate alongside an imaging sensor for left and right view acquisition. The binocular system is then experimentally characterized for 3D object imaging under incoherent near-infrared light. This work provides a feasible route toward miniaturized and low-complexity three-dimensional depth-sensing systems, with potential applications in compact security monitoring and intelligent vision terminals.

用于深度传感的双目低畸变超透镜

超表面提供了一个有前途的解决方案，紧凑和轻量级的双目深度传感。然而，现有的方法要么忽略了成像质量和几何畸变对精度的影响，要么依靠复杂的后处理进行校正和细化。在这里，我们提出了一个低畸变的双目超透镜系统的深度传感没有后端校正算法。一对与偏振无关的硅基超透镜，设计为30°视场和&；lt；0.20%的最大畸变，与用于左右视图采集的成像传感器一起单片集成在单个基板上。然后对双目系统在非相干近红外光下的三维物体成像进行了实验表征。这项工作为实现小型化、低复杂度的三维深度传感系统提供了一条可行的途径，在紧凑型安全监控和智能视觉终端中具有潜在的应用前景。

期刊介绍： Applied Physics Letters (APL) features concise, up-to-date reports on significant new findings in applied physics. Emphasizing rapid dissemination of key data and new physical insights, APL offers prompt publication of new experimental and theoretical papers reporting applications of physics phenomena to all branches of science, engineering, and modern technology. In addition to regular articles, the journal also publishes invited Fast Track, Perspectives, and in-depth Editorials which report on cutting-edge areas in applied physics. APL Perspectives are forward-looking invited letters which highlight recent developments or discoveries. Emphasis is placed on very recent developments, potentially disruptive technologies, open questions and possible solutions. They also include a mini-roadmap detailing where the community should direct efforts in order for the phenomena to be viable for application and the challenges associated with meeting that performance threshold. Perspectives are characterized by personal viewpoints and opinions of recognized experts in the field. Fast Track articles are invited original research articles that report results that are particularly novel and important or provide a significant advancement in an emerging field. Because of the urgency and scientific importance of the work, the peer review process is accelerated. If, during the review process, it becomes apparent that the paper does not meet the Fast Track criterion, it is returned to a normal track.
