中文摘要：
采用自制的光固化材料制作了光导纤维作为传感段,两端分别与光纤耦联后埋入光固化材料中,构成光纤折射率传感器.以He-Ne激光输入光纤,输出端采用光电探测器接收光功率,固化过程中,传输光的衰减程度表征了光固化材料的固化情况.实验测得该光固化材料的临界曝光量为193.8s.mw/cm2.实验结果表明,采用该方法能够较精确测量光固化材料固化一定深度的曝光时间,简单易行,为实时监测光固化材料的固化程度提供一种新方法.
英文摘要：
The critical exposure is one of the basic parameters of the performance of the light curing material.A new measurement method was designed and used to measure the critical exposure of the light curing material that was made by ourselves.The refractive index of the light curing material that has been cured is slightly bigger than that of the light curing material which is uncured.So a section of optical fiber was made by the cured light curing material and immersed in the uncured material,which constituted a...
