Abstract

Photoacoustic imaging transducer with a pair of wavelength-matched Bragg gratings (forming a Fabry-Perot cavity) inscribed on a short section of microfiber has been developed. A tunable laser with wavelength that matched to one of selected fringe slopes was used to transmit the acoustic induced wavelength. Interferometric fringes with high finesse in transmission significantly enhanced the sensitivity of the transducer even under very small acoustic perturbations. The performance of this novel transducer was evaluated through the imaging studies of human hairs (similar to 98 mu m in diameter). The spatial resolution is 300 mu m. We have demonstrated that the novel transducer developed in this study is a versatile tool for photoacoustic imaging study.
