TL;DR: In this article, the point spread function as a function of frequency was characterized for point source reconstruction and Galactic dust mapping using the Q \& U Bolometric Interferometer for Cosmology (QUBIC) and the authors concluded that spectro-imaging performance is nearly optimal up to five sub-bands in the case of QUBIC.

TL;DR: In this article, the design, manufacturing and performance of the horn-switch system developed for the technological demonstrator of QUBIC (the $Q$\&$U$ Bolometric Interferometer for Cosmology).
Journal ArticleDOI
The Gaussian beam mode analysis of off-axis aberrations in long wavelength optical systems
TL;DR: In this article, a matrix-based scheme using Gaussian beam mode analysis (GBMA) for predicting aberrations from off-axis mirrors is presented. But the accuracy of these scalar GBMA predictions is limited.
Proceedings Article

TL;DR: In this article, the authors present the optical design of the High Frequency Instrument (HFI) together with the optical performances measured during the ground calibration campaigns, and report on the evolution of the knowledge of the pre-launch HFI beam patterns when coupled to the telescope, and on their significance for the HFI data analysis procedure.
