Ultra-High-Speed Optical Fiber Sensor Can Monitor Structural Health in Real Time

Facebook Twitter LinkedIn Email Comments
TOKYO, Jan. 31, 2017 — A real-time fiber-optic distributed sensing system for monitoring strain and temperature in physical structures has been developed, which requires light injection from only one end of the fiber. The novel sensing system demonstrated a sampling rate of 100 kHz, an improvement of over 5,000 times the conventional rate. Optical fiber sensors based on Brillouin scattering show promise as a technology for monitoring the condition of structures because they are highly sensitive and stable and can be used for distributed strain and temperature measurements. However, real-time distributed...Read full article
