Abstract

A powerful aberration correction toolbox for intensity error correction is presented enabling restoration of the beam uniformity and the beam shape. The proposed method, referred to as intensity adaptive optics (I-AO), features the design of a dual-loop feedback control system that can function in both a sensor-based and sensorless mode. The feasibility of the approach is validated with quantitative analysis of the focal quality for an aberrated system, using both compensation methods, and paves the way for a new avenue for AO technology. These findings will benefit a wide range of applications spanning from aerospace to microscopy.
