-
The mFL.12 is currently at Technology Readiness Level (TRL) 7–8.
-
Developed within the framework of FRANCE 2030 with ADEME support.
-
Successfully tested in Venice during the ESA PHY2FLEX campaign (7–9 October 2025), confirming its performance and robustness under marine conditions.
The mFL.12 is a miniature active optical sensor for in-situ laser-induced fluorescence (LIF) measurements in aquatic environments. Designed for integration on USVs and AUVs and operable to 600 m depth, it offers high sensitivity, low power consumption, and built-in connectivity for long-term autonomous water-quality monitoring.
Its hyperspectral LiDAR architecture enables measurements both below the surface and through surface films, allowing direct detection of oil slicks and subsurface emulsions — capabilities not achievable with traditional remote sensing.
Compact and energy-efficient, the mFL.12 can operate on fixed platforms or small mobile systems such as USVs, AUVs, and drones, extending fluorescence monitoring into environments previously inaccessible to conventional instruments.
