摘要
通过对逆反射相关术语定义和测试系统的分析研究和不同旋转角下反光膜光度性能的测试计算,认为旋转角是逆反射测试技术中的重要术语,对逆反射材料测试的影响十分显著。在逆反射材料测试中引入旋转角,将规范和完善逆反射测试方法,消除因材料方向性而造成的光度性能测量误差,指导对反光膜等逆反射材料的质量评价和正确使用。
By analyzing retroflection vocabulary and testing system and computing photometric characteristics in different rotation angles,it is considered that rotation angle is an important vocabulary in testing technology of retroreflection and its influence on retroreflection testing is significant.Adding the item of rotation angle into retroreflection testing will normalize and perfect the test method of retroreflection to eliminate the measurement error of photometric performance caused by material directivity,and induct quality evaluation and appropriate use for retroreflective materials such as retroreflective sheeting.
