Final engineering test for AdOpt@TNG

摘要

Abstract: The adaptive optics modules for the Italian Telescopio Nazionale Galileo, namely AdOptTNG, is ready to be mounted at the telescope. First light will take place with the tip- tilt loop working, about which further laboratory test has been made during the last month. Also, the speckle camera with the real time autocorrelation feature has been completely finished and tested. The tracking system which allow to use moving references has been completed. For what regards the higher order loop the contracts about the DM and the CCD controller have been successfully concluded. Moreover, the wavefront sensing unit has been in large part built and tested in the laboratory. Details of the integration in the Nasmith Interface carrying the CCD scientific camera and the IR Imager are given together with a thorough description of the internal acceptance test of the optomechanical module comprising more than 20 motorized axes and several functioning modes. !16
