摘要：

We present spatially weighted optical fiber sensors that filter specific vibration modes from one-dimensional beams placed in clamped-free and clamped-clamped configurations. The sensitivity of the sensors is varied along the length of the fiber by tapering two-mode, circular-core fibers. Selective vibration mode suppression on the order of 10 dB has been obtained using weighted sensors. We describe experimental results and propose future applications for distributed sensors.
