Optimal wavefront shaping [PDF]
, 2022 The holy grail of biomedical optical imaging is to perform microscopy deep inside living tissue. Biological tissue scatters light, which prevents the formation of a sharp focus. Wavefront shaping (WFS) makes it possible to focus light through or inside turbid media by spatially shaping the incident wavefront. In this thesis, we tackled some of the most

Wavefront shaping: A versatile tool to conquer multiple scattering in multidisciplinary fields [PDF]
The Innovation, 2022 Optical techniques offer a wide variety of applications as light-matter interactions provide extremely sensitive mechanisms to probe or treat target media. Most of these implementations rely on the usage of ballistic or quasi-ballistic photons to achieve

Wavefront shaping for glare reduction
Optica, 2016 Scattering of light by random media limits many optical imaging and sensing applications, either by scrambling waves that carry images or by generating glare—background noise that hinders detection. In recent years, it was shown that the shaping of the wavefront of light before it enters the scattering environment allows an unexpected degree of control

Enhanced Depth of Focus Intraocular Lenses: Through Focus Evaluation of Wavefront-Shaping versus Diffractive Optics [PDF]
Biomedicine Hub, 2023 Introduction: A new class of nondiffractive, wavefront-shaping Enhanced-Depth-of-Focus (EDoF) IOLs has been introduced very recently to cope with photic phenomena known from diffractive EDoF IOLs.

Optical wavefront shaping based on functional metasurfaces [PDF]
Nanophotonics, 2020 Regarded as a kind of smart surfaces, metasurfaces can arbitrarily tailor the amplitude, phase, and polarization of light. Metasurfaces usually consist of subwavelength nanoantenna or nanoresonator arrays, which are delicately designed and processed.
