Dataset for "All-fibre wavefront sensor"
, 2022 We have developed a tip-tilt wavefront sensor based on a tapered three-core optical fibre. In this device, a coupled region at the sensing tip of the fibre converts phase information from an incoming wavefront into intensity information within each of ...

Advanced Functional Materials, EarlyView.The mantis shrimp telson reveals how ridged biological shields control deformation under impact. Inspired by this architecture, telson‐inspired ridged curved shells transform ridge geometry and macroscopic curvature into bidirectional snap‐through, tunable stiffness, and enhanced hysteretic energy dissipation for multifunctional architected materials ...

Advanced Functional Materials, EarlyView.Printed negative‐dielectric‐anisotropy liquid‐crystal droplets enable multidimensional full‐vectorial optical‐field sensing across polarization, phase, and wavelength, while also generating tunable skyrmionic‐like complex optical fields. ABSTRACT Adaptive manipulation of vectorial optical fields is important for optical metrology, imaging, and ...

A Digital Prism-based Wavefront Sensor Testbench [PDF]
, 2019 In this paper, we present a simulation framework for a digital prism-based wavefront sensor. In simulation, we generate a digital prism wavefront sensor (3-sided, 4-sided and cone) and compute the linearity of the 3-sided digital prism wavefront sensor

An Optical Wavefront Sensor Based on a Double Layer Microlens Array
Sensors, 2011 In order to determine light aberrations, Shack-Hartmann optical wavefront sensors make use of microlens arrays (MLA) to divide the incident light into small parts and focus them onto image planes.

Moiré‐Induced Symmetry Breaking of Charge Order in van der Waals Heterostructures
Advanced Materials, EarlyView.A uniaxial moiré potential in misfit (MS)1+δTaS2 heterostructures selectively reshape charge order: the embedded 1H‐TaS2 layer hosts an incommensurate charge‐density wave, fragmented into nanometer domains and stripped of threefold symmetry. Superconductivity, however, remains uniform and fully gapped, revealing heterosymmetry stacking as a selective ...
