Classical and quantum approaches to power spectrum measurement bydiffractional methods,

摘要

Abstract: Power spectrum measurements by diffractional methods with classical and quantum description of electromagnetic signals are considered. Classical aspects of spectral measurements (SM) theory is based on classical approximation of exact quantum representation of signal and spectrum analyzer (SA) description in terms of linear system theory. Quantum aspect of SM theory considers SM process as transformation temporal statistics of photons to their space distribution statistics, performed by SA. !32
