III Matrix Treatment of Partial Coherence

摘要: Publisher Summary The study of partially coherent wave fields by means observable quantities such as the auto- and cross-correlation functions amplitude forms an important area progress in modern optics. properties are treated a method using positive semi-definite Hermitian matrix. An intensity matrix is constructed for quasi-monochromatic field. Its transformation due to optical transmission, detection practical photodetectors, then described. mutual considered this chapter operator functional space, shown be equivalent matrix, vector space. There exists apparent parallelism between various expansion theorems connect two procedures. One advantages treatment over ordinary one involving possibility straightforward derivation thermodynamic entropy fields. This achieved terms principal waves representing eigenvalues Various prescribing degree incoherence entire field can also easily derived.
