Abstract:
Adaptive optics (AO) systems correct atmospheric turbulence in real time and they are normally designed for large telescopes but not for modest due to their cost. In this paper, we propose a portable AO instrument, named ALIOLI, capable of be installed in different medium and small-sized telescopes. The novelty of this new instrument is the modularization of its components which allows great flexibility in the design, being possible easily adapt the instrument to the working telescope or observing technique by adjusting each module independently. Here we present the instrument concept and a preliminary design for its installation in the Carlos Sanchez Telescope (! 1.5m, Teide Observatory (Canary Islands)). The Wavefront Sensor (WFS) module is intended to be used with three different WS, Shack-Hartmann, Two Pupil Plane Position and non-modulated Pyramidal, allowing a joint configuration for comparative studies. A comparison of the response of these sensors has been carried out by simu
lating the instrument in Python. The simulation results demonstrate the goodness of the applied algorithms and the higher linearity and precision of the SH WFS in comparison with the others two.
