摘要
本文的主要目的在综合评述近年来在光的相干性方面研究的成就。表明光子简并度和相干度等在有关问题中起重要作用,诸如干涉、拍频、强度起伏等。由于辐射过程的随机性质,拍频信号的强度由过程的相关度决定;由于光子是玻色子,这就决定了强度起伏中有相关项。从已有实验结果看来,光的相于性完全可从量子力学的基础概念得到解释。
In this paper, recent advances in the research of coherence properties of electromagnetic radiation are discussed. Using the conception of photon degeneracy and degree of coherence the author is able to explain many problems such as light mixing, intensity fluctuations and the properties of coherent light source. Since the occurrence of radiation process is at random, the intensity of the signal generated by the mixing of different sources can be determined by the correlation of radiation processes as derived in the present paper. Regarding photons as bosons, the phenomena "intensity interferense" is explained as quantum fluctuations. The coherence properties of radiation may thus be interpreted well on the basic conception of quantum machanics.
