Fiber Optic Sensing Systems for Railways

The praetorian fiber optic sensing for railways can detect rail deformation, cracks, intrusion, and track health. HAWK's fiber optic systems for railways can monitor any strain and stress change on events leading up to an eventual rail breakage event, as well as deformation of the track due to heat or loss of ground support. It can also detect the sound of locomotives, locate the train's position and speed, and identify sound anomalies due to moderate track surface defects.

Principle of Operation

Using a combination of Rayleigh backscatter and time of flight, Praetorian fiber optic sensing for railways determines the presence, location, intensity, and frequency of vibrations along an optical fiber in real time.

Rayleigh backscatter responds to physical vibration imparted on the fiber by disturbances to the application. HAWK’s signal analysis software allows Praetorian to determine the most likely origin of the vibration quickly and report any nefarious signals to security personnel without notifying an intruder of their detection.
