Implication

Experimental study demonstrates rapid ultrasonic velocity measurement in liquids using laser beam deflection, highlighting a high-precision noncontact acoustic testing approach.

Key Points

Develop a noncontact, fast, and highly accurate optical method to measure ultrasonic velocity across various liquids.
Generated an acoustic pulse in liquid samples using a pulsed laser beam.
Monitored sound wave propagation by recording deflection angles on two parallel, displaced continuous-wave probe laser beams.
Tested acoustic velocities across varying temperatures in ethanol, methanol, water, and concentrated sulfuric acid.
Achieved an acoustic velocity measurement accuracy of 5 parts in 10^4 within a total measurement duration of 100 μs.
Determined temperature-dependent acoustic velocity curves for ethanol, methanol, water, and previously unmeasured concentrated sulfuric acid.
