Abstract
We present a method for a reconstruction of Wigner functions of quantum mechanical states of light on different observation levels. Using the Jaynes principle of Maximum Entropy we show how to reconstruct the Wigner function on the given observation level which is characterized by mean values of a set of observables. We present examples illustrating the power of the proposed method. In particular, we analyze the reconstruction of Wigner functions of coherent states, squeezed states, Fock states, and superpositions of coherent states on various observation levels of physical relevance.
