Wavefront phase retrieval with multi-aperture Zernike filter for atmospheric sensing and adaptive optics applications

Behzad Bordbar, Nathan H. Farwell, Mikhail A. Vorontsov

Open publisher page 5 citations

Abstract

A novel scintillation resistant wavefront sensor based on a densely packed array of classical Zernike filters, referred to as the multi-aperture Zernike wavefront sensor (MAZ-WFS), is introduced and analyzed through numerical simulations. Wavefront phase reconstruction in the MAZ-WFS is performed using iterative algorithms that are optimized for phase aberration sensing in severe atmospheric turbulence conditions. The results demonstrate the potential of the MAZ-WFS for high-resolution retrieval of turbulence-induced phase aberrations in strong scintillation conditions for atmospheric sensing and adaptive optics applications.
