Abstract
For the precise measurements of high intensity megahertz ultrasonics, we propose a new microphone/hydrophone using a sharply bent optical fiber, "Hairpin Fiber Microphone". It has abilities to overcome some problems in conventional microphones. In this report, operation mechanism of the proposed sensor is studied experimentally over a wide frequency range. Considering the application to high-frequency ultrasonics, a miniaturized sensor with the diameter of 1mm is made for trial, and its performance is demonstrated.
