چکیده
Tunable Diode Laser Absorption Tomography (TDLAT) is a non-intrusive measurement technique for determining two-dimensional spatially resolved distributions of temperature and species concentration in high enthalpy flows. TDLAT combines infrared laser absorption spectroscopy with tomographic image reconstruction. Having previously been implemented at the University of Virginia's Aerospace Research Laboratory supersonic combustion tunnel, the TDLAT technique is now utilized for experimentation on NASA Langley’s Direct-Connect Supersonic Combustion Test Facility. The tomographic reconstruction of an opaque object as well as preliminary spectral data is presented. Ongoing experimentation on NASA
