Zusammenfassung:	The present invention relates to an acceleration measuring system using an optical fiber, in which an accurate earthquake simulation is achieved by accurately measuring acceleration in the three axial directions, power supply on a detecting unit is unnecessary, the configuration is simple, maintenance is almost unnecessary due to improved durability, and a remote control is available. The present invention provides an acceleration measuring system including: a weight matter; an elastic member having one end fixed to the weight matter and an opposite end connected to an object to be measured with acceleration; and an optical fiber extending parallel to the elastic member, having one end connected to the object and an opposite end connected to the weight matter, and including a ring shape part as a portion of the optical fiber. 본 발명은 3축 방향의 가속도를 정확하게 측정하여 정확한 지진모사가 가능하며, 감지부에 전원 공급이 필요치 아니하고, 구성이 간단하고, 내구성이 향상되고 유지 관리가 거의 불필요하며, 원격에서도 운용될 수 있는 광섬유 가속도 측정 시스템을 제공하기 위한 것으로서, 본 발명에 따르면, 질량체; 상기 질량체에 일단이 고정되고 타단은 가속도를 측정하고자 하는 대상 물체와 연결되는 탄성 부재; 및 상기 탄성부재와 나란하게 연장되고, 일단은 상기 대상 물체와 연결되고, 타단은 상기 질량체와 연결되는 광섬유의 일부분으로서, 링 형상부를 구비하는, 상기 광섬유를 포함하는, 가속도 측정 시스템이 제공된다.
