【摘要】 为了测试有机光导纤维的光损耗(Attenuation)值,我们研制了LOFT-1型激光有机光导纤维光损耗测试仪(以下简称LOFT-1型仪)。本文对LOFT-1型仪的工作原理、结构组成、主要技术指标、主要特点等作了简单介绍。同时对仪器的应用范围、测量原理、影响测量准确度的主要因素和提高仪器灵敏度的主要途径等有关问题进行了初步探讨。更多还原

【Abstract】 Light attenuation is an important parameter. To determine the light atten- uation value of plastic optic fiber, we have developed the Model LOFT-1 Laser Optic Fiber Test Apparatus. This paper briefly describes the working princi- ple, basic structures, major technical specifications, major characteristics and applications of Model LOFT-1 Test apparatus. Meanwhile the range of app- lication, principle of measurement, measuriug accuracy and methods for in- creasing sensitivity were discussed in this paper.更多还原
