碩士 === 國立高雄第一科技大學 === 光電工程研究所 === 95 === In recent years, in-fiber bragg gratings (FBG) have been widely used in sensing applications. The sensors of bare in-fiber bragg gratings (FBG) as the major skeleton have become the most important technique of interests . As a pressure sensor, the bare in-fiber bragg gratings (FBG) have the limit of pressure sensoring. To attend the goal of practice , some researches have been done by some unique packagings of he bare in-fiber bragg gratings (FBG) in order to improve and increase the sensitivity of pressure measurements . In this thesis, we made a sensor of the bare in-fiber bragg gratings (FBG) as the major skeleton by ourselves . And on the out abroad of it attaches six kinds of polymer mechanisms in different ratio (1:5、1:10、1:13、1:15、1:17、1:20) . Through effective packagings, we discovered that there would be the best sensitity of pressure measurments in the ratio of 1:13. Compared to the complete bare in-fiber bragg gratings (FBG),the sensitity increased in about 9700 times .
