Paper Abstract

High resolution imaging in ground-based astronomy is limited by the wave front degradation through the turbulent atmosphere. Adaptive optics offers the possibility to overcome these limitations. It employs a real-time phase compensation with a phase shifting optical element, which is usually a deformable mirror. The information for the control of the mirror surface is gained from a wavefront sensor. Thispaper describes an adaptive optics prototype for infrared imaging using a visible wavefront sensor and its expected performances in astronomy.
