      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.},
