| Outline of Final Research Achievements |
Dynamics of water content in a biological tissue is important information of a biological activity. In the research, we first verified the Beer-Lambert law in the near-infrared optical coherence tomography because it can detect only the light keeping the coherency that propagates rectilinearly and is retro-reflected from scatters. Second, we investigated quantitative measurement of the water content distributed in a biological tissue using a double-wavelengths optical coherence tomography system in the time domain. Finally we built up the fast spectral-domain optical coherence tomography system, which can process spectroscopically the double-wavelengths interference intensities at the same time. The potential of the double-wavelengths optical coherence tomography system was demonstrated in imaging the temporal variation of the water content distributed in the tissue of plants.
