摘要

Abstract

Adaptive optics (AO) is a powerful tool employed across various research fields

from aerospace to microscopy. Traditionally

AO has focused on correcting optical phase aberrations

with recent advances extending to polarisation compensation. However

intensity errors are also prevalent in optical systems

yet effective correction methods are still in their infancy. Here

we introduce a novel AO approach

termed intensity adaptive optics (I-AO)

which employs a dual-feedback loop mechanism to first address non-uniform intensity distribution and subsequently compensate for energy loss at the pupil plane. We demonstrate that I-AO can operate in both sensor-based and sensorless formats and validate its feasibility by quantitatively analysing the focus quality of an aberrated system. This technique expands the AO toolkit

paving the way for next-generation AO technology.
