Abstract

A systematic and quantitative analysis is given of the impact of pupil aberrations on the imaging performance in wavefront manipulation applications using adaptive optical elements. For the practical case of rotationally-symmetric types of wavefront corrections, such as defocus or spherical aberration, analytical expressions of the induced aberrations are derived including their pupil and field dependence. Each aberration is thereby related to the specific pupil aberration present at the adaptive element. The results can be used to specify the acceptable amount of pupil correction required for a specific magnitude and type of wavefront manipulation.

Summary

Introduction

The technology of adaptive optical elements, such as spatial light modulators or deformable mirrors, has rapidly improved. The footprints of all ray bundles are identical there, and all field points are affected in the same manner by the element For such application, the considered optical system must provide an accessible pupil plane. A systematic and quantitative approach is still missing, describing both the induced types of image aberrations and the acceptable amount of pupil aberrations depending on the specific wavefront manipulation being done. In this paper, such systematic overview and a quantitative analysis is given of the impact of pupil aberrations on wavefront manipulation with adaptive phase elements
