    "abstract": "In this thesis we present a direct scheme for measuring quasidistribution\nfunctions of light. This scheme, based on photon counting, is derived from a\nsimple relation linking the Wigner function with photon statistics. We develop\na full multimode theory of the scheme, and show that the principle of the\nmeasurement can be straightforwardly generalized to the detection of the\nmultimode radiation. We also discuss practical aspects of the scheme, including\nstatistical error, non-unit detection efficiency, and imperfect interference\nvisibility. Next, we report experimental realization of the scheme, and present\nmeasurements of the Wigner function for several quantum states of light.\nFinally, we study the general problem of statistical uncertainty in\nquantum-optical photodetection measurements.",
