    "abstract": "We investigate exponential phase moments of the s-parametrized\nquasidistributions (smoothed Wigner functions). We show that the knowledge of\nthese moments as functions of s provides, together with photon-number\nstatistics, a complete description of the quantum state. We demonstrate that\nthe exponential phase moments can be directly sampled from the data recorded in\nbalanced homodyne detection and we present simple expressions for the sampling\nkernels. The phase moments are Fourier coefficients of phase distributions\nobtained from the quasidistributions via integration over the radial variable\nin polar coordinates. We performed Monte Carlo simulations of the homodyne\ndetection and we demonstrate the feasibility of direct sampling of the moments\nand subsequent reconstruction of the phase distribution.",
