Partially reflecting optical fiber splice for temperature and strain measurement
摘要
An optical fiber device for allowing local measurement of temperature or strain using pulse amplitude techniques. The apparatus includes a fiber splice having a high temperature epoxy or solder to secure the opposing fibers in spaced relationship within a metal tube. By applying heat or stress to the tube the load causes the air gap to open or close which in turn varies the amount of light transmitted. By utilizing apparatus to measure the change in the amplitude affected by changes in the air gap, one can measure ultimately the strain or temperature imposed on the device.
