分析了光纤端面倾斜对光能量耦合的影响和光纤接收角的变化。
The influence of inclination of the fiber end surface to coupling energy of a pyrometer and variation of the accepting Angle of the fiber caused by the inclination is calculated.
沿光纤光轴传输到光纤倾斜端面上的光将被全反射，同时被光栅衍射。
The light propagating along the axis of the fiber incident on the angled end will be totally reflected and diffracted.
