Researchers at Purdue University have developed a new method for measuring gas temperature within 5 nanoseconds. The technique features optical emission spectroscopy (OES) in conjunction with a probing nanosecond plasma pulse to measure bulk gas temperature with great spatial and temporal resolution. Purdue researchers have demonstrated that it is physically feasible to establish pulsing probe parameters so that gas heating by the probing pulse itself is negligible, whereas the emission from the probing plasma is sufficient to conduct the OES measurements and conduct the temperature measurement.
