Abstract
A new thermometry has been proposed based on time-of-arrival measurements of acoustic waves associated with laser-induced sparks. The two laser sparks separated by known distance were produced simultaneously, then the arrival times of resulting acoustic waves were measured using a high-frequency response microphone installed in the same plane and line of the laser sparks. Because the speed of sound is basically a function of temperature, the temperatures of the region between the two laser sparks were inferred from the difference in arrival times between the acoustic waves from each of the two sparks.
