Vectorial adaptive optics: a new tool for aberration correction (Invited Paper)

Abstract
Adaptive optics normally concerns the feedback correction of phase aberrations. Such correction has been of benefit in various optical systems, with applications ranging in scale from astronomical telescopes to superresolution microscopes. Here we extend this powerful tool into the vectorial domain, encompassing higher dimensional feedback correction of both polarisation and phase. This technique is termed vectorial adaptive optics (V-AO). This technique pushes the boundaries of traditional scalar beam shaping by providing feedback control of extra vectorial degrees of freedom. This paves the way for next generation AO functionality by manipulating the complex vectorial field.

supervisor at the University of Oxford. He runs the Vectorial Optics
and Photonics Group, which focuses on optical techniques for
vectorial beam manipulation, including structured light, structured
matter, adaptive optics, and polarization sensing. He completed his DPhil degree in the
Department of Engineering Science at the University of Oxford from 2018-2020 (within two years)
and was later elected as a Junior Research Fellow in Engineering at St John’s College (1
st place among all candidates). He has published over 70
scientific papers, including first- and corresponding-authored papers in Light: Science &
Applications, Nature Communications, Optica, Advanced Photonics, elight, etc.
