| Research Abstract |
We conducted a study to realize the selective spectral analysis at a local area in strong scattering medium, such as biological tissues. In two years study, we have developed a technique to quantitatively measure the optical absorption at a local area in the body. This result opened the new possibility; for the non-invasive transcutaneous measurement of accurate optical absorption; and for the tissue spectral measurement while eliminating the effect of the interstitial tissue. We have reported these results in academic journals and international/domestic conferences, and applied patents.
