Abstract
We show that the exponential phase moments associated with the s-ordered ge neralized Wigner function can be sampled from homodyne data for s less than or equal to 0. The tomographic sampling functions are evaluated for non-un it homodyne quantum efficiency, and the statistical reliability of the reco nstruction is tested by Monte Carlo simulated experiments. The reconstructi on of the a-ordered phase distribution from sampled moments is discussed, a nd the reduction of statistical fluctuations by adaptive techniques is also analysed.
