【摘要】 太阳辐射光谱中红外光的能量约占太阳总辐射能的一半以上,玻璃光纤由于吸收损耗很难传输红外光;塑料光纤又承受不了太阳能产生的高温,本文介绍一种耐热温度高,传输效率高的传能光导-外镀膜耐热空芯光导.它是利用有机材料的高透光性能和无机材料的耐高温性能,在熔融条件下实现材料性能的重组,形成有机-无机复合耐热空芯光导,耐热温度可达150～200℃.由于光是在空芯内传播,光导的传光效率提高了20%～23%,而且可以传输红外光.本文重点分析了外镀膜耐热空芯光导的耐热性能。更多还原

【Abstract】 In solar radiation spectrum , the energy of infrared light account for over half of the sun total energy. The glass optical fiber is very much difficult to transmit the infrared light due to absorption loss, The plastic optical fiber can not bear the high temperature that the solar energy produces. This paper introduces a kind of heat-resisting hollow optical fiber outside plated film, It can bear the high temperature (150~200℃) and transmits light with high efficiency. Utilizing high transparent performance of organic material and bearing high-temperature performance of inorganic material, under melting condition material performances are reorganized and organic- inorganic compound heat-resisting hollow optical fibers which heat-resisting temperature can be up to 150-200℃ degrees Centigrade are formed. Because sunlight is transmitted in the hollow core , transmitting efficiency is increased from 30%~677% to 70%~83%, and can transmit the infrared light. This paper analyzes the heat-resisting performance of the hollow outside film-plated heat-resisting optical transmitter.更多还原
