摘要
本文探讨自发参量下转换双光子场的产生机理，研究基于自发参量下转换相关双光子绝对测量红外光源辐射功率的原理和方法。
The generation mechanism of spontaneous parametric down conversion(SPDC)biphoton field is discussed theoretically.The correlated photons produced in the SPDC process have been used in the absolute measurement of infrared spectral radiance.The measurement principle and method are introduced.
