Wavefront Sensing

Background:

Shack-Hartmann wavefront sensors (SHWS) are standard for non-interferometric wavefront measurement.
High-slope wavefronts cause spot crosstalk and distortion, leading to centroiding errors and limiting dynamic range versus accuracy.
Existing methods struggle with severe aberrations and spot loss.

Purpose of the Study:

To develop a computational model for precise wavefront reconstruction with Shack-Hartmann sensors under challenging conditions.
To overcome the inherent conflict between dynamic range and accuracy in SHWS for high-slope wavefronts.
To enhance the robustness and measurement range of SHWS for complex aberrations.

Main Methods:

A graph-theoretic computational model (G-SHWS) was developed using bipartite graph matching to accurately map spots to subapertures.
A Graph Attention Network (GAT) was integrated, encoding matching topology and utilizing spatial/morphological spot features.
The model minimizes global pairing cost to approximate true spot distribution and correct centroiding errors.

Main Results:

G-SHWS extended the measurable dynamic range of SHWS by 21 times the conventional limit.
Reconstruction error was maintained below $0.05 λ$ even with severe spot loss.
The method demonstrated high-precision reconstruction for strongly distorted wavefronts.

Conclusions:

G-SHWS provides a robust computational framework for large dynamic range wavefront sensing.
The model significantly enhances SHWS capabilities for measuring complex aberrations.
This approach overcomes limitations of traditional SHWS in dynamic range and accuracy.
