Kurzfassung
We present an adaptive optics approach to improve the image quality of telescopes observing targets through atmospheric turbulences. Intended as an enhancement for off-the-shelf imaging systems an f/10 achromatic lens telescope is expanded by relay telescopes and dichroitic beam splitters to satisfy the adaptive optics requirements. A high speed Shack-Hartmann wavefront sensor and an adaptive membrane mirror are located in conjugated planes. A non-deterministic PC system provides a fast closed-loop frequency of 500 Hz. The system characteristics are investigated and first results in terms of wavefront diagrams and resolution charts are presented.
