Abstract:

Noncontact techniques of optical probing of photoacoustic pulses provide new opportunities for ultrasonic andor spectroscopic measurement in hostile environments e.g., flames, corrosive fluids, dangerous aerosols, etc. and also basic understanding of photoacoustic generation processes. This paper provides examples of such applications in the new field of optical ultrasonics whereby ultrasonic determinations of flows, temperatures, etc., are measured optically, including optical ultrasonic spectroscopy whereby ultrasonic dispersion and relaxations are measured optically.
