    "abstract": "We provide a simple analytic relation which connects the density operator of\nthe radiation field with the number probabilities. The problem of\nexperimentally \"sampling\" a general matrix elements is studied, and the\ndeleterious effects of nonunit quantum efficiency in the detection process are\nanalyzed showing how they can be reduced by using the squeezing technique. The\nobtained result is particulary useful for intracavity field reconstruction\nstates.",
