【摘要】：为比对全积分球和半积分球在光路传输、输出信号上的差异,根据积分球基本原理分别建立了全积分球和半积分球的光学传输模型,推导了两种积分球在光纤探测方式下的输出信号强度表达式,并从理论和实验上对这两种积分球的探测性能进行了比对。结果表明,全积分球与半积分球的输出信号和探测灵敏度均与积分球涂层反射率、积分球半径、光纤数值孔径角有关;半积分球性能是否优于全积分球取决于漫反射涂层以及平面反射镜反射率的选取。当理想情况下平面反射镜的反射率等于1时,半积分球的信号强度是全积分球的2倍。
[Abstract]:In order to compare the difference of the optical transmission and the output signal between the whole integral sphere and the half integral ball, the optical transmission models of the whole integral sphere and the half integral sphere are established according to the basic principle of the integral sphere. The expression of the output signal strength of the two kinds of integration spheres under the optical fiber detection mode is derived, and the detection performances of the two kinds of integration spheres are compared theoretically and experimentally. The output signals and detection sensitivity of the total and semi-integrated spheres are related to the reflectivity of the coating, the radius of the integral sphere, and the numerical aperture angle of the fiber. Whether the semi-integral sphere is superior to the full integral sphere depends on the selection of the diffuse reflection coating and the reflectivity of the plane reflector. The reflectivity of the plane reflector is 1:00 under ideal conditions. The signal intensity of the half integral sphere is twice that of the total integral ball.
