Sensitivity of a photodetector employing signal heterodyning in a photomultiplier
Abstract
Analytical expressions are obtained for the sensitivity of a photodetector of modulated optical radiation based on a photomultiplier circuit with heterodyning; nonlinear distortions of the electrooptical modulator are taken into account. The operation of the heterodyne detector is compared to that of a direct-detection receiver. The advantages of the former detector are described.
