| 520 | _ | _ | |a 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. |
