Various diagnostic methods, including those optically based such as laser spectroscopy and velocimetry, and those non-optically based such as mass spectrometry and chromatography, provide essential experimental observations for combustion and fluid mechanics studies. Along with the development of lasers and optoelectronic devices,a wide range of diagnostics is being developed to probe the key parameters, e.g., temperature, pressure,velocity,species concentrations, etc., in harsh or complicated combustion and flow fields, which are otherwise difficult to access with traditional sampling methods. Fundamental physics of light-matter interactions including absorption, emission, scattering, ionization, etc., need to be understood to interpret the measurement. Advanced signal processing algorithms and control technology are employed to implement the sensors and measurement systems for experimental studies of chemical kinetics, turbulence, combustion and propulsion systems, as well asinstrumentations for energy systems and more applied fields.
