Once upon a time, there were radio and optical astronomers, each group with its own way of detecting and thinking about radiation. In spite of the shock treatment administered by Hanbury-Brown and Twiss more than thirty five years ago, this dichotomy persists to a surprising extent even today. As new techniques emerge, we clearly need to do better. Coherent and incoherent detection, heterodyning and interferometry are all situations where a full analysis involves quantum behaviour of the radiation. This informal review covers the general approach needed and goes over some points of principle which arise.

8 ‘Coherence and Fluctuations of Light’- Mandel, L. and Wolf, E., Eds. Dover (1970) is an excellent reprint collection with many of the early and basic papers on coherence and quantum optics upto 1966 including refs. [5], [6] and [9]. In particular, one can find here a third distribution on phase space, given by Husimi and Kano, which has the virtue of not going negative.Google Scholar
9 Aharonov, Y. et al. Annals of Physics, 34, 498 (1966) Notice however that the model of a beam splitter used by these authors has no “fourth port” and this, at least in my view, makes their characterisation of coherent states more mathematical than physical.CrossRefGoogle Scholar
10 Yamamoto, Y. et al. Progress in Optics, 28, 89, Ed. Wolf, E., North Holland (1990) - is a fascinating review article on the brave new world of quantum - limited optical measurements, squeezed states, etc., including actual experimental realisations. I cannot resist passing on a piece of Zen wisdom from this source which is relevant to reference [9] above. When one taps a waveguide to let some signal out, one inevitably lets the vacuum (i.e., mode ground state) in through the fourth port !.Google Scholar
