초록
압력이 인가되는 지점에만 장주기 광섬유 격자가 형성되는 광섬유 소자를 제작하였고, 제작된 소자의 특성을 조사하였다. 제작된 소자는 720 μm 주기의 격자가 윗면에 형성되어 있는 60 cm 길이의 금속막대와 고무덮개로 구성되어 있으며, 압력이 인가될 때에 압력이 인가된 지점에만 장주기 광섬유 격자가 형성되었고 인가된 지점에 관계없이 동일한 투과특성을 가지는 장주기 광섬유 격자들이 형성되었다. 그리고 제작된 소자의 특성측정을 통하여 무게를 측정할 수 있는 광섬유 로드(Load)센서로 사용 가능함을 보여 주었다.
Abstract
An optical fiber device is fabricated that is formed LPFGs only where pressure is applied, and the characteristics of the device are investigated. The fabricated device is composed of a 60cm-long metallic rod, with long period gratings of 720μm on the upper side and a rubber cover. In this device, gratings are only formed when pressure was applied to a spot, to which pressure was applied, and the formed gratings had the same transmission property regardless of spot, to which pressure was applied. We measured the optical transmission property of the fabricated device and found its usability as an optical fiber load sensor to measure weight.
