由于与正常光源相比，来自活体生物体的光子发射极其微弱（光子通量小于10-15W的量级），因此已经建立了一些非常灵敏的方法和装置来检测活体生物体上的生物光子的整体发射强度和发射的二维图案。本章将讨论各个研究小组使用的现代技术和系统，对细胞、组织甚至器官等活体生物体的超弱光子发射进行检测、光谱分析和二维成像。此外，生物系统的光子发射具有一些与非生命系统不同的内在特征，例如相干性。因此，需要一些特定的方法来表征生物系统光子发射的物理和生物特征。
Since photon emission from living organisms is extremely weak (the photon flux is the order of less than 10-15 W) in comparison with a normal light source, some very sensitive methods and devices have been established to detect biophotons both in integral emission intensity and the twodimensional pattern of the emission on living organisms. This chapter will discuss the modern technology and systems used by various research groups to perform the detection, spectral analysis and two-dimensional imaging of ultraweak photon emission from living organisms such as cells, tissues and even organs. In addition, photon emission from biological system has some intrinsic features, such as coherence, differing with that from non-living systems. Thus, some particular methods are needed to characterize the physical and biological features of photon emission from biological systems.
