Abstract

Laser-induced fluorescence (LIF) measurement of OH density requires an independent calibration to generate a coefficient that accounts for systematic errors. We have demonstrated the use of thermal dissociation of HsO in a high-temperature atmospheric air furnace for OH density calibration. At temperatures above 1500 K, the density of OH, which is in chemical equilibrium with naturally-occurring water vapor, is sufficient for LIF measurement.
