摘要: 采用数值模拟方法,对光纤纤芯半径分别是3μm,5μm,10μm,15μm,光纤半径都是20μm的光纤进行计算机模拟,并得到了相对反射光强在光纤入射平面上的分布曲线。其结果表明,对半园型液面计中反射式半圆形探头最佳耦合结构的半径满足ρmax=R-0.01004a3+0.37429a2-3.38095a+16.85714(μm)

Abstract: The best coupling structure of the reflective-type-semicircular-optical fiber probe has been studied by using the method of numerical simulation. Distributive curve of the intensity of the reflective light on the incident plane of the light is given by computer simulation to the different radii of optical fiber cores which are separately 3μm, 5μm, 10μm, 15μm. and the radius of the optical fibers are totally 20m. The results show that the best coupling radius of the reflective type semicircular optical fiber probe satisfies the formula. ρmax=R-0.01004a3+0.37429a2-3.38095a+16.85714(μm).

Key words: numerical simulation, optical fiber probe
