The aim is to simultaneously measure nitric oxide concentration and temperature for combustion diagnostics.
Utilized a quantum cascade laser scanning from 1929.4 to 1931.3 cm⁻1.
Developed an algorithm to analyze overlapping absorption signals and correct baseline errors.
Validated measurements against thermocouples and electrochemical sensors.
Achieved consistent measurement agreement with thermocouple data across temperatures from 603 to 653 K.
NO concentration results aligned with data from a 1.3 µm tunable diode laser absorption spectrometry (TDLAS) method.
Demonstrated reduced system complexity and enhanced reliability even in high-humidity conditions.
