Rotational temperature and nitrogen number density are measured in a low pressure, 55 K, Mach 10 hypersonic air flow. The data are recorded using a non-linear optical technique named Dual-Line Coherent Anti-Stokes Raman Scattering (DLCARS). DLCARS allows single laser-shot spatially-resolved measurements. The flow is probed from the free stream to the vicinity of a two-dimensional model. Averaged temperature and density profiles are compared with those predicted by a Navier-Stokes solver.
