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193.8 s·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.

Abstract:: The optical fiber is made of self-made light-curing material as the sensing section, and the two ends are coupled with the optical fiber and buried in the light-curing material to form the optical fiber refractive index sensor. With He-Ne laser input fiber, photodetector is used at the output end to receive optical power, and the degree of attenuation of transmitted light characterizes the curing of light-curing materials during the curing process. The critical exposure of the light-curable material was measured as 193.8 s·mw/cm2. The experimental results show that this method can accurately measure the exposure time of the light-curable material at a certain depth, which is simple and easy, and provides a new method for real-time monitoring of the curing degree of the light-curable material.
