Abstract

This paper develops optimal statistical estimation formulation for multidither adaptive optics control loops which potentially can enhance stable beam control performance in the presence of spurious signal-like noise. A multidither autofocus example is chosen to compare estimated assisted and conventional adaptive optical performance in the presence of speckle-generated noise.
