Rapid wavefront shaping using an optical gradient acquisition [PDF]

open access: yesNature Communications
Wavefront shaping systems enable deep tissue imaging by correcting scattering aberrations, but estimating optimal modulation correction is challenging, since it depends on the unknown tissue structures.

Ultrafast all-optical second harmonic wavefront shaping [PDF]

open access: yesNature Communications
Optical communication can be revolutionized by encoding data into the orbital angular momentum of light beams. However, state-of-the-art approaches for dynamic control of complex optical wavefronts are mainly based on liquid crystal spatial light ...

Fast holographic scattering compensation for deep tissue biological imaging

open access: yesNature Communications, 2021
Wavefront shaping is used to overcome scattering in biological tissues during imaging, but determining the compensation is slow. Here, the authors use holographic phase stepping interferometry, where new phase information is updated after each ...

Shaping elastic wavefront through zigzag-folded metasurfaces

open access: yesFrontiers in Physics, 2023
We present a reconfigurable elastic metasurface design composed of an array of zigzag-folded sheets with parallel corrugations to control the wavefront of the refracted A0 Lamb mode wave.
