Non-Intrusive and Quick Response Thermometry Using Laser-Induced Thermal Acoustics (LITA)

Using laser-induced thermal acoustics, we demonstrate to measure non-invasively and remotely the speed of sound and temperature ranging from 278 K to 341 K in water at atmospheric pressure. The accuracy of measured the speed of sound and temperature is formed to be 3% and 4%, respectively. Single-sh...

Zusammenfassung:Using laser-induced thermal acoustics, we demonstrate to measure non-invasively and remotely the speed of sound and temperature ranging from 278 K to 341 K in water at atmospheric pressure. The accuracy of measured the speed of sound and temperature is formed to be 3% and 4%, respectively. Single-shot precisions based on three standard deviation of 20 samples were within 4% for the speed of sound and the temperature. The time resolution for each measurement was 300 ns.
