Abstract
A fiber optic vibration sensor based on Multimode Interference (MMI) effects is demonstrated. The proposed sensor is tested by characterizing its bending response, impulse response, and its response to fixed external frequencies. Induced vibration is measured in the range from 0 Hz to 2.5 kHz; the main frequency component overcomes on the first and second harmonics with a difference of 32.4 dB and 37.2 dB, respectively.
