Abstract

We present progress and results for the pyramid wavefront sensor unit on the Large Binocular Telescope's Interferometer (LBTI). The system is a clone of the pyramid sensor unit developed at Arcetri Observatory for the LUCIFER instrument. We discuss the performance of simulated reconstructors during preliminary on-sky testing at the MMT. These reconstructors were generated with the code AOSim2, a customizable end-to-end simulator of a telescope and its AO system. We used the 3-5μm imager Clio to take fast exposures at 3.8μm, from which we calculated Střehl Ratios (SR) for each pyramid configuration and for the Shack-Hartmann (SH) system currently installed. We obtained instantaneous SR as high as 60% for the pyramid as compared to 65% mean for the SH. We identify improvements which will increase the SR in future implementations. These tests demonstrate the feasibility of commissioning a pyramid wavefront sensor on LBTI using a synthetic reconstructor.
