Abstract :
A fast, high-resolution fibre Bragg grating sensing system for weigh-in-motion applications is presented. The interrogator uses standard telecom photonic components and employs signal processing to improve the accuracy down to 1 . The system has been applied to a speed bump, achieving an excellent reproduction of the bump structural deformations.
