Abstract
The well-known schemes for simultaneous measurement of canonically conjugate variables in quantum optics based on beam-splitting, amplification and heterodyning are analysed in the Heisenberg picture. It is shown that the operators representing the measured observables share a common structure. The measured phase-space probability is a non-negative smoothed Wigner function.Keywords
