| Abstract(in English) | Fundamental study was conducted to obtain structural and functional information in a biological body using light and ultra-sound. The low coherence interferometry technique was applied to suppress the effect of the optical scattering between the modulated point and light incidence/output points. The characteristics of a measurement system and the delectability of the modulated signal by the proposed method were investigated. It was shown experimentally that the detectable depth of the modulated signal increased with the increase of the coherence length of a light source. In a phantom experiment, the interface of scattering discontinuity could be detected. Through this study, the effectiveness of the proposed method was verified. |
