abstract = {This work introduces a novel method to significantly reduce
the number of measurements needed for wavefront correction
in strongly scattering media, as compared to traditional
approaches. The key innovation lies in defining the beam
using an annular angular spectrum rather than a 2D grid. We
employ a Spatial Light Modulator (SLM) for both the
preparation and sampling of the annular angular spectrum.
The speckle pattern of the transmitted beam is evaluated at
a single point of a detector, and the phase distribution is
measured using three-step interferometry. The final
correction to the transmitted beam is achieved by applying
the conjugate phase onto the initial beam defined on the
spatial light modulator. Remarkably, 64 measurements already
provide a reasonably effective wavefront correction.
However, optimal results are attained when the spatial
azimuthal sampling frequency of the angular spectrum matches
the transverse wave vector of the generated quasi-Bessel
beam.},
