标准摘要
[中文适用范围]： IEC 61300 的这一部分旨在表征测量阶跃折射率多模波导光源@的环形角通量，其中大多数横模被激发。在本标准中，术语波导被理解为包括通道波导和光纤，但不包括平板波导。环绕角通量 (EAF) 是在一定立体角内从阶跃折射率多模波导芯辐射的总光功率的分数。 EAF 是作为数值孔径全角的函数来测量的。基本方法是使用校准相机收集每次测量的二维远场数据，并将它们以数学方式转换为环形角通量。 [外文原描述]： IEC 61300-3-53:2015 is intended to characterize the encircled angular flux of measurement step index multimode waveguide light sources, in which most of the transverse modes are excited. The term waveguide is understood to include both channel waveguides and optical fibres but not slab waveguides in this standard. Encircled angular flux (EAF) is the fraction of the total optical power radiating from a step index multimode waveguide's core within a certain solid angle. The EAF is measured as a function of the numerical aperture full angle. The basic approach is to collect, for every measurement, two dimensional far field data using a calibrated camera and to convert them mathematically into encircled angular flux. Keywords: encircled angular flux (EAF), measurement step index multimode waveguide light sources
