Optical tomography of Fock state superpositions

We consider optical tomography of photon Fock state superpositions (FSS) in connection with recent experimental achievements. The emphasis is put on the fact that it suffices to represent the measured tomogram as a main result of the experiment. We suggest a test for checking the correctness of experimental data. Explicit expressions for optical tomograms of FSS are given in terms of Hermite polynomials. Particular cases of vacuum and low-photon-number state superposition are considered and the influence of thermal noise on state purity is studied.
