In this paper, the main features and fundamental concep- tions of biophotonics were introduced basically. Then the coherence theory of biophoton emission was reviewed. Furthermore, based on this coherence concept, the quantum theory of traditional Chinese medicine （TCM） and properties of Chinese medicinal herbs were presented. To show the nature of biophoton emission in living systems and clarify its basic detection mechanism, high sensitive detection system which allows non-invasive and non-destructive （or less） recording was finally presented.展开更多
