    "abstract": "We propose a general method for measuring an arbitrary observable of a\nmultimode electromagnetic field using homodyne detection with a single local\noscillator. In this method the local oscillator scans over all possible linear\ncombinations of the modes. The case of two modes is analyzed in detail and the\nfeasibility of the measurement is studied on the basis of Monte-Carlo\nsimulations. We also provide an application of this method in tomographic\ntesting of the GHZ state.",
