Abstract
A simple and efficient method for direct sampling of the density matrix of a signal mode in optical homodyne tomography is developed. The method is based on approximate, quasianalytical techniques of Fourier transform and yields the density matrix in an arbitrary field-strength basis. It is also suitable for direct sampling of density matrices of matter systems in generalized position or momentum bases. © 1996 The American Physical Society.Keywords
