The first includes communication engineers and scientists and students of communication theory who need to cope with basic problems arising in communication with optical signals. The ultimate detectability of optical signals and the accuracy with which their parameters can be estimated cannot be ascertained by the methods of detection theory that apply at radio frequencies; the fundamental concepts of the theory must be revised, and this book shows how. The second group of readers comprises physicists interested in the foundations and applications of quantum mechanics, for whom it may be fruitful to consider quatum measurement as a process of decision among alternative density operators, or as an estimation of certain parameters of the density operator of a quantum system. May they find the problems analyzed here a challenge to their conceptions of the quantum theory. ER -
