| 摘要 |
A noninvasive pulsed fluorescence gas velocimeter (10) that determines dynamic parameters of a gas flow from detection of fluorescence re-radiation of excited molecules (20, 26, 28) of the gas. The present invention has higher altitude capability than devices that utilize particulate scattering. The velocimeter requires no probes and utilizes a laser or other light source (50) that does not perturb the gas flow being measured.
