Scientific paper

The choice of coherent or incoherent detection for a given application at submillimeter and far infrared wavelengths is discussed. Both methods are comparable in sensitivity and technological feasibility over this spectral range. No one type of detection of filtering is superior for all applications at these wavelengths. Detailed tradeoffs in terms of resolution and detector availability are considered in determining whether Fourier transform, grating, Fabry-Perot, or heterodyne instruments will be best suited to a given task.
