  • Measurement system and temperature and/or shape change sensor using brillouin scattering analysis
    Patent number: 10697807
    Abstract: A measurement system for performing measurement by Brillouin scattering analysis, the system comprising a laser emitter device (10) configured to emit an incident wave (?0) and a reference wave (?0??B), the incident wave presenting an incident frequency (?0) and the reference wave presenting a reference frequency (?0??B), the reference frequency (?0??B) being shifted from the incident frequency (?0) by a predetermined value (?B). The system is configured to: project the incident wave (?0) into the optical fiber (25); receive in return a backscattered wave (?0??S); generate a composite wave (?0-S, 0-B) combining the backscattered wave (?0??S) and the reference wave (S0??B); and determine at least one property relating to the fiber by analyzing a Brillouin spectrum of the composite wave (?0-S, 0-B). Advantageously, the incident wave and the reference wave come from a dual-frequency vertical-cavity surface-emitting laser source (12) forming part of the laser emitter device.
