| Abstract(in English) | Ultrasound-modulated light has recently been utilized to improve a spatial resolution of optical imaging of biological tissues. This paper describes a method for detecting the ultrasound-modulated light by using variations in speckle patterns. A pulsed laser beam was injected into a turbid medium and modulated by an ultrasound pulse. The pulsed loght was synchronized with the ultrasound, and a phase inversion technique was used so that a modulated component could be detected using a conventional CCD camera. To evaluate the usefulness of this technique, one-dimensional imaging of absorbing object embedded in a turbid medium was carried out in both of transmission and reflection methods. It was found that a modulated component can be extracted from scattered light by the proposed technique in both cases. |
