Adaptive Optics

Enhanced Wavefront Corrected Ophthalmic Imaging

We aim to develop adaptive optics (AO) algorithms from astronomy in order to substantially improve speed and image quality as well as to increase field of view of state-of-the-art ophthalmic AO imaging systems for retinal imaging.The goal is to characterize the clinical robustness of these novel diagnostic AO systems by in vivo clinical experiments.

Tomography in astronomical applications

Point-spread function of the Extremely Large Telescopes with AO correction.

In this subproject we consider the improvement of the imaging process of ground based astronomical telescopes by AO systems and the reconstruction of the Interstellar Matter distribution in our galaxy. We focus on the analysis of models and the development of fast and highly accurate methods for the inversion of wavefront sensor data and the reconstruction of the turbulence profile of the atmosphere above ground based telescopes. An extension of the developed methods toward ophthalmic AO imaging is planned.
