  • We present a non-metallic interferometric silica optical fiber ultrasonic wideband sensor for optoacoustic imaging applications. The ultrasonic sensitivity of this sensor has been characterized over the
    frequency range from 1 to 10 MHz. A comparative analysis has been
    carried out between this sensor and an array of piezoelectric
    transducers using optoacoustic signals generated from an optical
    absorbent embedded in a tissue mimicking phantom. Also, a two
    dimensional reconstructed image of the phantom using the fiber
    interferometric sensor is presented and compared to the image obtained
    using the Laser Optoacoustic Imaging System, LOIS-64B. The feasibility
    of our fiber optic based sensor for wideband ultrasonic detection is
