Abstract

Adaptive optics (AO) systems correct atmospheric turbulence in real time and they are normally used in large and medium telescopes but not in modest telescopes due to their size and cost. Here we propose a portable AO instrument capable of being installed in different medium and small-sized telescopes. The novelty of this new instrument is that it is based on the modularization of its components: simulator/calibrator, Wavefront Corrector (WFC) with a deformable mirror (DM) and Wavefront sensor (WFS) modules. This modular concept allows great flexibility in the design, being possible to easily adapt the instrument to the working telescope or instrument by adjusting each module independently. This concept also makes possible the comparison between different types of WFS such as Shack-Hartmann (S-H), Two Pupil Plane Position (TP3) or Pyramidal. Here we present the optical design and expected performance of the three WFS for 1.52m, Carlos Sanchez Telescope (TCS), and the preliminary results of the S-H sensor in laboratory and the first on-sky test.
