Multiplexed wavefront sensing with a thin diffuser [PDF]
Optica, 2023 In astronomy or biological imaging, refractive index inhomogeneities of e.g. atmosphere or tissues induce optical aberrations which degrade the desired information hidden behind the medium. A standard approach consists in measuring these aberrations with

Wavefront sensing for objective assessment of vision therapy efficacy: Preliminary results [PDF]
EPJ Web of Conferences, 2023 The aim of this study was to use wavefront sensing to objectively evaluate the effects of vision therapy in subjects with insufficiency (AI) and infacility of accommodation (AINF). Aberrometry was performed with a Shack-Hartmann wavefront aberrometer for

Focal-plane wavefront sensing with photonic lanterns I: theoretical framework [PDF]
Journal of the Optical Society of America B, 2022 The photonic lantern (PL) is a tapered waveguide that can efficiently couple light into multiple single-mode optical fibers. Such devices are currently being considered for a number of tasks, including the coupling of telescopes and high-resolution ...

Phase diversity-based wavefront sensing for fluorescence microscopy
bioRxiv, 2023 Fluorescence microscopy is an invaluable tool in biology, yet its performance is compromised when the wavefront of light is distorted due to optical imperfections or the refractile nature of the sample. Such optical aberrations can dramatically lower the

Method for distortion correction of multi-layered surface reconstruction using time-gated wavefront sensing approach [PDF]
Journal of the European Optical Society-Rapid Publications, 2013 In order to estimate the multi-layer surface profile and to detect the inter-layer surfaces defects, gated wavefront sensing approach has been proposed in the previous works [1, 2].
