Optical characterization and adaptive optics correction of polymer adaptive lens aberrations.

ABSTRACT

Adaptive lenses based on fluid-filled polymer membranes allow for great simplification of optical systems providing large focal length variation and reduction of size, weight, and power consumption. However, aberrations can reduce their optical quality and, for some demanding applications, their correction by means of adaptive optics implies increased complexity, especially if reflective wavefront correctors are used. In this work, we characterize two adaptive lenses in terms of optical power and aberrations. We then correct the gravity-induced aberrations by means of a multiactuator adaptive lens in a closed-loop adaptive optics configuration, with a minimal increase in optical setup complexity. The improvements in the performance of an imaging system are shown.
