Abstract

We show preliminary results of the implantation of a stabilized Michelson interferometer for the characterization of ultrasonic transducers. The detection system consists of a Michelson interferometer in which a feedback system has been integrated to set the interferometer at the linear region of detection and to compensate optical phase changes introduced by environmental vibrations; this allows us to work in the most sensible region of the system and obtain output signals proportional to the detected displacements (< 10 nm). The obtained results show that it is possible to detect ultrasonic displacements close to 0,2 nm in a bandwidth of 3 MHz using a He-Ne laser with an output power of 1 mW. Preliminary characterization of ultrasonic displacements generated by an ultrasonic transducer immersed in a water tank was performed using this interferometer.
