Using the Q-branch rotational-vibrational cars signal from the N2 molecule, temperature profiles in Ch4/air and Ch4/NeO premixed flames have been obtained. Additionally temperatures have been determined for H2 and CH4 diffusion flames using the CARS signal from the Q-branch of H2. Several possible experiments in ballistics (muzzle flash and propellant strand burning) are discussed in the report. 收起
