摘要:
设计一种侧面发光塑料光纤表面正四棱锥形微结构散射点,使侧面发光塑料光纤可用作裂隙灯显微镜的裂隙光源,以减小裂隙光源的体积.采用光学仿真软件分析光纤上表面(有散射点)和光纤下表面(无散射点)的散射率,当塑料光纤直径为1 mm时,得到优化后的正四棱锥散射点的底边宽度和深度均为80 μm.仿真结果表明,光纤下表面散射光的光束发散角在垂直于光纤方向约为40°,在平行于光纤方向约为110°,经过焦距为50 mm的投射镜会聚后的光带宽度约为0.3 mm,可以满足裂隙灯显微镜的要求.
Abstract:
A kind of regular pyramid microstructure scattering point is designed on the surface of side-glowing plastic optical fiber, so that the side-glowing plastic optical fiber can be used as the slit light source of slit lamp microscope to reduce the volume of slit light source. The optical simulation software is used to analyze the scattering rate of the upper surface(with scattering points)of the optical fiber and the lower surface(without scattering points)of the optical fiber. When the diameter of the plastic optical fiber is 1 mm, the width of the bottom edge and depth of the optimized regular pyramid scattering point are both 80 μm. The simulation results show that the beam divergence angle of the scattered light on the lower surface of the optical fiber is about 40° in the direction perpendicular to the optical fiber and about 110° in the direction parallel to the optical fiber, and the light band width after being converged by the projector with a focal length of 50 mm is about 0.3 mm, which can meet the requirements of slit lamp microscope.
