Background:

Adaptive optics systems require efficient wavefront reconstruction for large-scale applications.
Existing distributed methods face challenges in accuracy and robustness.

Purpose of the Study:

To introduce and evaluate the distributed-spline-based aberration reconstruction (D-SABRE) method.
To assess D-SABRE's performance against existing distributed methods in adaptive optics simulations.

Main Methods:

Decomposing the wavefront sensor domain into multiple partitions.
Utilizing multivariate splines for local wavefront reconstruction within each partition.
Comparing D-SABRE with the distributed cumulative reconstruction (CuRe-D) method using the YAO simulation tool.

Main Results:

D-SABRE achieves accuracy within 1% of global methods.
The method demonstrates a speedup that scales quadratically with the number of partitions.
D-SABRE outperforms CuRe-D in accuracy at low decomposition levels and shows greater robustness to loop gain variations.

Conclusions:

D-SABRE is a highly accurate and efficient method for distributed wavefront reconstruction.
The method is well-suited for large-scale adaptive optics systems.
D-SABRE offers a robust alternative to existing distributed reconstruction techniques.
