Multifunctional Imaging with an Inverse-Designed Nonlocal Metasurface
Lincoln Clark, Yang Xu, Cat-Uyen Phan +6
Nonlocal metasurfaces enable all-optical processing of spatial information in optical fields. Here, we demonstrate a topology-optimised metasurface that switches between phase-cont…
Wavelength and Polarization Multiplexed Nonlocal Metasurface for Quantitative Phase Microscopy
Haiwei Wang, Shikun Ma, Shaban B. Sulejman +6
Imaging transparent samples remains an ongoing challenge in the study of unstained biological cells and material samples. Widely used methods trade off system complexity, cost and…
Quantum Phase Gradient Imaging Using a Nonlocal Metasurface System
Jinliang Ren, Jinyong Ma, Katsuya Tanaka +4
Quantum phase imaging enables the analysis of transparent samples with thickness and refractive index variations in scenarios requiring precise measurements under low-light conditi…
Metasurfaces for infrared multi-modal microscopy: phase contrast and bright field
Shaban B. Sulejman, Lukas Wesemann, Mikkaela McCormack +9
Different imaging modalities are used to extract the diverse information carried in an optical field. Two prominent modalities include bright field and phase contrast microscopy th…
Reconfigurable Image Processing Metasurfaces with Phase-Change Materials
Michele Cotrufo, Shaban B. Sulejman, Lukas Wesemann +4
Optical metasurfaces have been enabling reduced footprint and power consumption, as well as faster speeds, in the context of analog computing and image processing. While various im…
Thin film notch filters as platforms for biological image processing
Shaban B. Sulejman, Niken Priscilla, Lukas Wesemann +5
Many image processing operations involve the modification of the spatial frequency content of images. Here we demonstrate object-plane spatial frequency filtering utilizing the ang…
Real time phase imaging with an asymmetric transfer function metasurface
Lukas Wesemann, Jon Rickett, Timothy J. Davis +1
The conversion of phase variations in an optical wavefield into intensity information is of fundamental importance for optical imaging technology including microscopy of biological…
Near-perfect absorber as a subwavelength thickness spatial frequency filter for optical image processing
Lukas Wesemann, Evgeniy Panchenko, Kalpana Singh +4
Spatial frequency filtering is a fundamental enabler of information processing methods in biological and technical imaging. Most filtering methods, however, require either bulky an…
