Abstract:

We present physical optics simulations of the dual-reflector submillimetre-wave telescope on the ESA PLANCK surveyor. The telescope is of a non-conventional Gregorian configuration, with two ellipsoidal reflectors providing a very large field of view at the focal plane where the array of 76 horn antennas feeding low-temperature detectors is located. We analyze defocusing effects of the system, polarization characteristics of the telescope, and the optical performance of high-frequency channels based on special multi-mode horns operating at 545 and 857 GHz.
