Asymptotic behaviour of the Strehl ratio in the presence of Zernike polynomial aberrations

Martin J Booth and Qi Hu


Through asymptotic analysis based upon the principle of stationary phase, we provide insight into the Strehl ratio response to single Zernike polynomial aberrations. It is shown that for Zernike modes with higher azimuthal orders, the asymptotic response shows slower convergence to zero. This has important implications for the design of iterative aberration correction methods, such as wavefront sensor less adaptive optics. © Anita Publications. All rights reserved.
