The Adaptive and Lucky Imagine Optics Lightweight Instrument (ALIOLI) is a portable Adaptive Optics (AO) system capable of being installed on different medium-sized telescopes due to a modular approach to its components. The Wavefront Sensor (WFS) module is designed to be used with three different WFSs: Shack-Hartmann (SH), Two Pupil Plane Position (TP3), and Pyramidal unmodulated, allowing a joint configuration for comparative studies of WFS response when different observing situations. In this article we show the assembly of the TP3 module and we summarize the first open-loop measurements on the bench. These results have been compared with those obtained in the simulation phase. Finally, we present the next proposed tests and the steps to follow for possible updates.
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.
