동적 변형률을 측정하고 실험적으로 평가하기 위해 광섬유를 따라 무작위 순서로 정렬된 임의의 거리로 측정 지점을 설정할 수 있는 Brillouin 광학 상관 도메인 반사 측정(BOCDR) 시스템을 제안합니다. 이 랜덤 액세스 시스템은 총 스트레인 측정 횟수 중 각 측정 지점에 측정 시간을 할당하여 측정 지점에 측정 대역폭을 할당할 수 있습니다. 이 할당된 숫자는 항상 동일하지는 않지만 서로 다른 고유 진동수를 갖는 복수의 물체에 필요합니다. 시스템을 검증하기 위해 서로 다른 고유 진동수를 갖는 두 개의 진동 물체의 변형률을 해당 물체에 부착된 하나의 광섬유로 측정했습니다. 시스템은 각 물체에 적절한 측정 대역폭을 할당하고 동시에 진동하는 물체에 해당하는 동적 변형률을 측정했습니다.

Abstract: A Brillouin optical correlation domain reflectometry (BOCDR) system, which can set measuring point to arbitrary distance that is aligned in a random order along an optical fiber (i.e., random accessibility), is proposed to measure dynamic strain and experimentally evaluated. This random-access system can allocate measurement bandwidth to measuring point by assigning the measurement times at each measuring point of the total number of strain measurements. This assigned number is not always equally but as necessary for plural objects with different natural frequencies. To verify the system, strain of two vibrating objects with different natural frequencies was measured by one optical fiber which is attached to those objects. The system allocated appropriate measurement bandwidth to each object and simultaneously measured dynamic strain corresponding to the vibrating objects.
