23. A method for measuring a load on at least one wheel of a vehicle, the method comprising:
-
a) installing at least one optical fiber with Bragg cells, forming a sensor for measuring deformations and comprising the Bragg cells, in a spring; b) emitting, by a source module, light signals toward each Bragg cell; c) each Bragg cell returning a light signal to a receiver module; d) converting, at the receiver module, the light signals into output data and transmits the output data to a processor module; and e) processing, at the processor module, the output data and calculating the load on the wheel equipped with the spring.
