Abstract

Post-dispersed Fourier transform spectrometers are prime candidates for up- coming far-infrared space telescopes, which achieve background limited spectral sensitivity by few-mode detectors. Straylight effects in such hybrid systems are investigated using a partially coherent modelling technique.
