Abstract: We provide a simple analytic relation which connects the density operator of the radiation field with the number probabilities. The problem of experimentally “sampling” a general matrix element is studied, and the deleterious effects of nonunit quantum efficiency in the detection process are analyzed showing how they can be reduced by using the squeezing technique. The obtained result is particularly useful for intracavity field reconstruction states.
