A thorough study on genetic algorithms in feedback-based wavefront shaping [PDF]

open access: yesJournal of Innovative Optical Health Sciences, 2019
Feedback-based wavefront shaping focuses light through scattering media by employing phase optimization algorithms. Genetic algorithms (GAs), inspired by the process of natural selection, are well suited for phase optimization in wavefront shaping ...

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.

Feedback-based wavefront shaping [PDF]

open access: yesOptics Express, 2015
Light scattering was thought to be the fundamental limitation for the depth at which optical imaging methods can retain their resolution and sensitivity. However, it was shown that light can be focused inside even the most strongly scattering objects by spatially shaping the wavefront of the incident light.
