Agil’Comb Sensing

The project Agil’Comb Sensing was a 2024 winner of the PREMATURATION call for projects, led by the Innovation Lab of IP Paris.

Fiber optic sensors rely on various physical phenomena (Rayleigh, Brillouin, and Raman scattering) to extract information such as temperature, strain, and vibration.

Each scattering mechanism typically requires a dedicated interrogator with specific optical and electronic configurations. This leads to increased system complexity and cost, redundancy in instrumentation, and limited flexibility in multi-parameter sensing applications.

Our technology leverages a single agile and optimized laser source integrated into one compact instrument, which provides:

• Unified multi-parameter sensing (Rayleigh, Brillouin, and Raman) without the need for multiple interrogators.
• Reduction in system complexity and cost by eliminating redundant hardware.
• Enhanced flexibility for diverse applications such as temperature, strain, and vibration monitoring. Improved sensitivity and potentially higher resolution, thanks to dynamic laser tuning and optimized signal processing.
• Scalable and easy-to-integrate design, enabling compact, robust solutions for industrial and research environments
