N2 - We propose a general method for measuring an arbitrary observable of a multimode electromagnetic field using homodyne detection with a single local oscillator. In this method the local oscillator scans over all possible linear combinations of the modes. The case of two modes is analyzed in detail and the feasibility of the measurement is studied on the basis of Monte Carlo simulations. We also provide an application of this method in tomographic testing of the Greenberger-Horne-Zeilinger state.
