    "abstract": "We describe the representation of arbitrary density operators in terms of\nexpectation values of simple projection operators. Two representations are\npresented which yield non--recursive schemes for experimentally determining the\ndensity operator of any quantum system. We suggest a possible experimental\nimplementation in quantum optics.",
