Abstract :

PILOT is a balloon-borne astronomy experiment designed to study the polarization of dust emission in the diffuse interstellar medium in our Galaxy at wavelengths 240 �µm and 550 �µm with an angular resolution of a few arc-minute. PILOT optics is composed an off-axis Gregorian type telescope and a refractive re-imager system. All optical elements, except the primary mirror, are in a cryostat cooled to 3K. We combined the optical, 3D dimensional measurement methods and thermoeslastic modeling to perform the optical alignment. I will present the system analysis, the alignment procedure, and finally the performances obtained during the second flight in March 2017.
