摘要: 光纖式感測技術可用來量測各種物理量的微小變動,如溫度、壓力、振動等,尤其對於應變和溫度變化的量測,又以布拉格光纖光柵(Fiber Bragg Grating, FBG)感測元件做成的感測器,更具有高靈敏度及高動態範圍。布拉格光纖光柵感測器製作過程中,需將布拉格光纖光柵與金屬基材執行接合動作。本研究使用低溫玻璃膠作為光纖與不鏽鋼金屬接合的接著劑接合研究,擬定出低溫玻璃膠接合時的塗佈方式、條件控制和限制等,作為應用在光纖光柵感測器之感測元件的接合參考。
Fiber-optic sensing technology can be used to measure a variety of small changes in physical quantities, such as temperature, pressure, vibration, especially for the measurement of strain and temperature changes. The sensor made of Bragg fiber grating (FBG) is especially appealing because of its high sensitivity and dynamic range. When making an FBG sensor, it is imperative that the FBG is properly bonded to the surface of the metal substrate. In this study, a low-temperature glass paste was used as a bonding agent to attach optical fiber to the surface of stainless steel diaphragm. The diaphragm along with the attached FBG were used as a sensing element in FBG based sensors. The coating method, condition control and limitations of low-temperature glass adhesive bonding were developed in this research.
