| Zusammenfassung: | The invention proposes an acoustic sensor device (1) with an optical fibre, comprising a casing (10) which delimits a cavity (3) and an optical fibre sensor (2), the optical fibre sensor comprising an optical fibre (12), the optical fibre extending through the casing between two points. Advantageously, the cavity (3) comprises a mixed fluid which comprises a liquid-based fluid and microballoons, the microballoons comprising gas bubbles. |
