SC646: Theoretical Foundations of Far-Infrared and Submillimetre-Wave Astronomical Optics: Modes, Coherence, and Photons
This course describes the theoretical foundations of far-infrared and submillimetre-wave astronomical optics. First the notion of coherent modal optics (Gaussian-Hermite, Gaussian-Laguerre, plane-wave, and Gabor-mode analysis) is introduced, and then a detailed procedure for modeling partially coherent optical systems, including sources and detectors, is described. A variety of advanced analytical techniques are presented (for example, how much power is coupled between two partially coherent beams? and how do we find the natural modes of a radiation field?), and the relationship to quantum optics is outlined. The concepts are demonstrated by explaining the modal principles of planar submillimetre-wave astronomical imaging arrays and multi-mode astronomical bolometric interferometers.
