摘要
理论分析了聚甲基丙烯酸甲酯(PMMA)塑料光纤受辐照后物理与化学性能的变化,并对2组塑料光纤样品进行了辐照前后光谱特性的研究及对比实验。分析了包层掺有PbO及纤芯材料特别提纯的塑料光纤以及一般塑料光纤的耐辐照特性和光谱恢复特性,发现纤芯的纯度及外包层的材料对塑料光纤的耐辐照特性具有很大的影响,这为耐辐照塑料光纤的研制提供了依据。
The physicaland chemical changes in PMMA POF after irradiation are analyzed theoretically, and the research and comparison analysis on the spectrum characteristics of two groups of POF sample are carried out before and after irradiation. The POF that the cladding is doped with PbO and the core is specially purified, and the radiation-resistant characteristics and recovery characteristics of general POFs are analyzed, it is found that the purity of the core and the cladding material have significant influence on POF＇s radiation-resistant performance. This results will provide the basis for the development of radiation-resistant POF.
