Abstract

The interaction of Pulsed High Enery Ultrasound (PHEUS) with biological tissues is the object of our research. To know more precisely how PHEUS interacts with tissues we must define the acoustical dose. Establishing such an acoustical dose requires exact measurement of the ultrasonic wave with amplitudes up to 100 MPa and its associated phenomena like acoustic cavitation. Therefore we have designed and built a laseroptic hydrophon. The principle of the design is to couple the light of a laserdiode into a fibre of quartz glass and to detect the wave induced variation of the refractive index in the medium at the end of the fibre. The sensitivity of the pressure gauge is 1.1 mV/MPa with a bandwidth of 10 MHz. Moreover, the rise and duration of cavitation bubbles which is dependent on the energy of the ultrasonic wave can be detected with the 50/125 u.m fibre.
