The molecular tagging velocimetry (MTV) is applied to a supersonic micro jet issuing from the orifice whose diameter is 500um. This velocimetry uses the forth harmonic of the Nd:YAG laser (266nm) as a light source to excite the acetone molecules seeded in the flow. The numerical flow simulation is performed to check the experimental result. As a result, the velocity profile measured by the present MTV system are found to agree with that calculated by the numerical flow simulation.
