In the present research, CARS (Coherent Anti-Stokes Raman Spectroscopy) measurement is applied to find out the characteristics of the non-equilibrium flow behind the strong shock waves generated at hypersonic velocities above 4km/s upto 5.8km/s. The rotational/vibrational temperatures for nitrogen molecules behind these velocities are calculated using the CARS signal obtained by experiments and are compared with the theoretical data obtained by in-house developed fitting program. In the present paper the spatial distribution of ro/vibrational temperatures obtained are presented along with the 2D radiation images captured.
