RT Journal Article T1 Variable Configuration Fiber Optic Laser Doppler Vibrometer System A1 Posada Román, Julio Enrique A1 Jackson, David A. A1 García Souto, José Antonio AB A multichannel heterodyne fiber optic vibrometer is demonstrated which can be operated at ranges in excess of 50 m. 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 switches PB Springer Nature SN 2190-7439 YR 2016 FD 2016-06-01 LK https://hdl.handle.net/10016/38977 UL https://hdl.handle.net/10016/38977 LA eng NO Author J.
