Application context: On-board monitoring of kerosene combustion residues
⇒ Optimization of fuel combustion + prevention of premature aircraft engine ageing
Technical challenges: Remote measurements, compact system, and operation in harsh environments
⇒ Development of a sensor based on a hollow-core anti-resonant fiber (HC-ARF), transparent in the mid-infrared (MIR) spectral range
Fiber design, fabrication, and characterization
⇒ Optical losses α<1 dB/m in the 4–5 µm spectral band (corresponding to the absorption bands of CO and CO₂), with bending losses compatible with the target application
Validation of a remote CO₂ sensor
⇒ Demonstration of the capability to measure the targeted CO₂ concentration range
