| Abstract: | By using Karhunen--Loeve expansion, cross--spectral density of light sourcefield is decomposed as quantum simple harmonic oscillator models,a new methodis developed in calculating entropy of light source field. By using this method,the entropy is calculated precisely for Gaussian Schell--model light source field,the relationship between the entropy and global coherence, and model numberof light source field is discussed. |
