| 摘 要： | 提出一种回归反射面材的新结构,以梯度折射率微球代替传统的超高折射率匀质玻璃微球.利用四阶Runge-Kutta方法进行光线追迹的理论计算,确定了制作新型回归反射面材的工艺参数.结果表明,按此条件制作回归反射面材可大幅度降低原先对折射率的过高要求,并显著提高回归反射的性能. |

| Abstract: | It is proposed a new structure of the retro-reflection plane material, in which the gradient index micro-spheres substitute for the traditional homogeneous glass spheres with high refractive index. Using the theoretical calculations of the light tracking by quadrivalence Runger-Kutta method, the technical condition of the retro-reflecting plane material of GRIN micro-sphere is obtained. The result shows that on this condition the former high demand for refractive index of medium can be highly reduced, and the function of retro-refraction of the material is improved greatly. |
