Intrinsic Limitations of Single Layer Polychromatic Metalens for Virtual Reality Visors
Myunghoo Lee, Ben Nguyen, Zhihao Zhou +7
Virtual and augmented reality (VR/AR) visors require compact and lightweight optics. Metalenses have been widely proposed as ultrathin replacements for bulky refractive eyepieces,…
Advantages of Broadband Metalenses for Generalizable Image Classification
Yubo Zhang, Johannes Fröch, Jinlin Xiang +6
Optical neural networks (ONNs) are gaining increasing attention to accelerate machine learning tasks. In particular, static meta-optical encoders designed for task-specific pre-pro…
Meta-optical Miniscope for Multifunctional Imaging
Zhihao Zhou, Khushboo Kumari, Ningzhi Xie +6
Miniaturized microscopes (miniscopes) have opened a new frontier in animal behavior studies, enabling real-time imaging of neuron activity while leaving animals largely unconstrain…
Computed tomography using meta-optics
Maksym Zhelyeznuyakov, Johannes E. Fröch, Shane Colburn +2
Computer vision tasks require processing large amounts of data to perform image classification, segmentation, and feature extraction. Optical preprocessors can potentially reduce t…
