Wavefront shaping through a free-form scattering object [PDF]
Wavefront shaping is a technique to study and control light transport inside scattering media. Wavefront shaping is considered to be applicable to any complex material, yet in most previous studies, the only sample geometries that are studied are slabs ...

Practical considerations for high-fidelity wavefront shaping experiments
Wavefront shaping (WFS) is a technique for directing light through turbid media. The theoretical aspects of WFS are well understood, and under near-ideal experimental conditions, accurate predictions for the expected signal enhancement can be given.

Wavefront shaping for forward scattering
Aberrations and scattering limit the ability of optical microscopy to penetrate deep tissues. Adaptive optics (AO) is a very effective technique to correct for smooth aberrations. Wavefront shaping (WFS) techniques, on the other hand, compensate both scattering and aberrations and have guaranteed convergence even for finding high ...

Nonlinear wavefront shaping with optically induced three-dimensional nonlinear photonic crystals
Generation of light with desirable amplitude and phase profiles with nonlinear wavefront shaping is important for optical technologies. Here, the authors demonstrate nonlinear wavefront shaping with three-dimensional nonlinear photonic crystals formed by

Depth-Resolved Wavefront Aberrations using a Coherence-Gated Shack-Hartmann Wavefront Sensor [PDF]
In the present paper we investigate the possibility of narrowing the depth range of a physical Shack - Hartmann (SH) wavefront sensor (WFS) by using coherence gating.

Wavefront shaping through emulated curved space in waveguide settings
Wavefront shaping is typically carried out outside the medium within which the beam is propagating. Sheng et al.exploit concepts inspired by General Relativity for wavefront shaping within optical waveguide settings, constructing narrow collimated beams ...

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

Mode conversion via wavefront shaping
In recent years, wavefront shaping has been utilized to control and correct distorted light for enhancing a bright spot, generation of a Bessel beam or darkening a complete area at the output of a scattering system. All these outcomes can be thought of as enhancing a particular mode of the output field. In this letter, we study the relation between the

Artificial intelligence-assisted light control and computational imaging through scattering media [PDF]
Coherent optical control within or through scattering media via wavefront shaping has seen broad applications since its invention around 2007. Wavefront shaping is aimed at overcoming the strong scattering, featured by random interference, namely speckle
