A possible experimental check of the uncertainty relations by means of   homodyne measuring photon quadrature
  We suggest to use the photon homodyne detection experimental data for checking the Heisenberg and Schr\"{o}dinger-Robertson uncertainty relations, by means of measuring optical tomograms of the photon quantum states.
