title = "Optical absorption measurement of biological tissues using ultrasound-induced light deflection",
abstract = "A measurement method based on ultrasound-induced light deflection is proposed for localized optical absorption characterization in biological tissues. In this method, a focused laser beam is incident perpendicular to the direction of ultrasound pulse propagation. By measuring the transmitted light intensity, temporal variations due to light deflection are detected. Since the measured waveform reflects the absorption characteristics around the laser light spot, localized absorption properties can be determined through computational analysis. We discussed the measurement principle using the Monte-Carlo simulations. The ultrasound pulse in the medium was modeled as a dielectric slab waveguides with graded index profile. Simulations with a virtual blood vessel phantom showed the highest sensitivity at a 1 mm depth under the skin.",
