中文摘要 | 本研究之主要目的在探討聚苯乙烯系塑膠光學纖維於鹽水噴霧環境之下,其光學 能量傳輸損耗之影響。我們選用聚苯乙烯作為塑膠光纖中心材料,外層包覆材料為聚甲基丙 烯酸甲酯,結果顯示,塑膠光纖之光學能量傳輸損失會隨著鹽霧試驗時間增加而增加,經七 個星期的測試,塑膠光纖之光學能量傳輸損失增加約 62.5 %,我們以水份測定儀來檢測材 料之吸水性,聚甲基丙烯酸甲酯材料之吸水性遠高於聚苯乙烯材料,故我們認為水份會擴散 進入聚甲基丙烯酸甲酯外層包覆材,因此,塑膠光纖之光學能量損失增加的主要原因為光線 在傳遞時,因為介面間水份的滲入造成光學散射的情況所致。 |
英文摘要 | The objective of this study is to investigate the attenuation loss of the plastic optical fiber (POF) with polystyrene core under harsh environmental conditions such as the salt spray test. The POFs consist of polystyrene core associated with the cladding of polymethyl methacrylate. The results have shown that the loss is increased with the increasing of time after salt spray test. The attenuation loss of wetted POF can increase up to 62.5% of dry POF after seven-week salt spray test. The Karl Fischer reagent apparatus was used to measure the amount of the absorbed water during the spray test. The amount of water absorbed by PMMA is much higher than that by PS. We conclude that the water diffuses into PMMA cladding. Therefore, the major factor resulting in the attenuation loss may be the scattering owing to the existing of particles and the uneven interface. |
