Paper Abstract

In this presentation, several ultrasound-modulated optical phenomena in a tissue phantom were observed by a pulsed ultrasound transducer. Some factors affected the modulated signal value were studied including the changing of the experimental conditions such as the distance between the focused volume of ultrasound beam and the detector as well as the frequency of ultrasound transducer. The experimental results and the analysis suggest that a compositive parameter concerning the intensity of the modulated signal, namely the modulation depth which is a key parameter to measure the scattering property even as a sensor to indicate the glucose concentration.
