The Heterodyne Instrument for the Far Infrared (HIFI) is a very high-resolution heterodyne spectrometer. It works by mixing the incoming signal with a stable monochromatic signal, generated by a local oscillator, and extracting the frequency difference for further processing in a spectrometer. The Heterodyne Instrument for the Far Infrared (HIFI) will have seven separate local oscillators covering two bands from 480-1250 gigaHertz and 1410-1910 gigaHertz. HIFI was developed by a consortium led by SRON (Groningen, The Netherlands).
