The system is designed to measure periodic signals, impacts, rotation, 3D strain, and vibration mapping. The displacement resolution of each channel exceeds 1 nm. The outputs from all channels are simultaneous, and the number of channels can be increased by using optical switches10eng© The Author(s) 2016.Atribución 3.0 EspañaVibrationMultiplexingLaser dopplerDigital processingNanometer resolutionOptical fiberresearch articleElectrónicaÓpticahttps://doi.org/10.1007/s13320-016-0293-0open access972106Photonic Sensors6AR/0000019803
