More Information
Summary:The present invention relates to an optical fiber displacement sensor having an optical sphere and a displacement sensing system using the same. According to the present invention, the displacement sensor having optical fiber having one or more optical spheres which has a larger diameter than the diameter of a core and is formed in a portion of the core. According to the present invention, the displacement sensor has a simple configuration and is capable of measuring displacement by comparing intensities of an input optical signal and the output optical signal using the single wavelength optical signal to as to be used for the displacement sensor in various fields. 본 발명은 광섬유 변위센서 및 이를 이용한 변위 센싱 시스템에 관한 것으로, 본 발명의 변위센서는 광섬유를 포함하는 변위센서로서 광섬유는 코어의 일부분에 코어의 직경보다 큰 직경을 갖는 하나 이상의 광학구체가 형성되어 있는 것을 특징으로 한다. 이러한 본 발명의 변위센서는 그 구성이 단순하고 단일 파장 광신호를 이용하여 입력 광신호와 출력 광신호의 세기 비교만으로 변위를 측정할 수 있어 다양한 분야에서 변위센서로서 활용될 수 있는 효과가 있다.
