摘要

与传统玻璃微珠埋入型膜结构相比，立方角锥型膜结构具有更高的逆反射效率，它是设计制作钻石级反光膜的基础。为满足不同的应用需求，需在标准立方角锥阵列的基础上施加某种结构变化，以增大有效入射角范围、降低逆反射系数的各向异性。建立膜结构与逆反射性能的联系，对指导、优化逆反射材料结构设计、缩短设计开发流程具有重要意义。基于光线追踪原理，计入光在传播过程中主要的损耗因素（有效投影截面、反射折射损失、偏振效应），编写了立方角锥型反光膜逆反射率计算程序。利用该程序分别计算了标准完整角锥、标准截角角锥以及对称轴倾斜一定角度的截角角锥的逆反射率，验证了程序的可靠性，证明程序在模拟的准确性、运行效率等方面较以往结果有明显提高。

Abstract

Compared with the traditional glass beads embedded type membrane structure, cube corner type membrane structure has higher efficiency of retroreflection, it is the foundation of designing and producing diamond grade reflective film. In order to meet different application requirements, we need to apply some change on the structure of the basic cube corner array, so as to increase the effective incident angle range, and to reduce anisotropy of retroreflection coefficient. Establishing the connection of membrane structure and the performance of the retroreflection is of great significance to improve the structure design of retroreflection material, which shortens the design and exploitation process. A program is written in order to calculate the retroreflectance of cube corner retroreflective sheeting. This program is based on ray tracing technology, primary light loss in the process of transmission(effective projection section, reflection and refraction loss)as well as the polarization effect is taken into account in this program. The retroreflection performance of several types of cube corner structures are anlalyzed by using the program, thus the reliability of the program is examined. It is also proved that the application of this program in the simulation can greatly improve the accuracy and efficiency than usual result.
