The purpose of this paper is to present a fiberoptic vibration sensor based on the monitoring of the mode distribution in a multimode optical fiber. Detection of vibrations and their parameters is possible through observation of the output speckle pattern from the multimode optical fiber. A working experimental model has been built in which all used(More)
The possibility of measuring amplitude and frequency of structural vibrations using a multimode optical fiber is demonstrated. By detecting and analyzing the variations in the output signal speckle pattern it is possible to detect vibrations and their parameters. A working experimental model has been built and tested. Components used for this system are(More)
Telemetry system based on embedded Linux single board computer (SBC) is presented. The basis of the system is an optical sensor for measuring amplitude and frequency of structural vibrations. Detection of vibrations and their parameters is possible through observation of the output speckle pattern from the multimode optical fiber. Optical sensor is(More)
