This study introduces a new method for wavefront-sensor-less adaptive optics (WFSless AO) systems. It efficiently corrects aberrations using system modeling and minimal intensity measurements, enhancing laser beam quality and image resolution.

Area of Science:

  • Optical engineering
  • Adaptive optics
  • Laser physics

Background:

  • Wavefront-sensor-less adaptive optics (WFSless AO) systems are crucial for improving laser beam quality and image resolution in scientific and medical applications.
  • A key challenge in WFSless AO is the absence of direct wavefront measurement, hindering efficient aberration correction.

Purpose of the Study:

  • To develop and validate an aberration correction approach for WFSless AO systems.
  • To address the challenge of efficient aberration correction without direct wavefront measurement.

Main Methods:

  • Utilized black-box system identification to model the WFSless AO system from input-output data.
  • Employed a small number of intensity measurements for aberration correction.
  • Validated the approach experimentally using static aberrations with Kolmogorov spatial distributions.
