文章介绍了印制光-电路板的测试方法，主要包括光波导的折射率测试、光传输损失测试、表面粗糙度测试、眼图测试、误码率测试、环境测试。
In the paper, the method of test about OE-PCB was reviewed. Including mainly Refractive Index, Optical Propagation Loss, Surface Roughness, Eye Pattern, Bite Error Rate test and Environment Impact.
仪器测试，通常是通过偏光仪来测试它的结构晶体，通过折射仪来测试它的折射率。
Instrument testing, usually by polarizing instrument to test the structure of its crystals, through the refractometer to test its refractive index.
结果表明，对聚合物分散液晶聚合物折射率的误差在5%以内，而对液晶体积分数的测试误差较大，达到10%左右。
The result indicates that the error of the test for refractive index of polymer is less than 5%, while for volume percent of liquid crystal, the maximum error reaches about 10%.
