Paper Abstract

A non-metallic interferometric silica optical fiber ultrasonic wideband sensor is presented for optoacustic imaging applications. We characterized the ultrasonic sensitivity of the optical fiber sensor within the frequency range of 1 to 5 MHz. We compared detection of real world optoacoustic signals, generated from an optically absorbing object embedded in a tissue mimicking phantom, between our sensor and an array of piezoelectric transducers. Reconstructed two dimensional acoustic images of the phantom are presented and compared with images obtained with the Laser Optoacoustic Imaging System, LOIS-64B, demonstrating the feasibility of our fiber optic sensor as a wideband ultrasonic sensor.
