| Research Abstract |
We studied to extract spectral components for the identical behavior by taking the correlation between each wavelength of the parameter. In this method the preliminary processing is unnecessary. Though it is difficult that the features are judged by the human when the parameter is over two. It is possible to carry out the spectrum analysis of the complicated system which followed many parameters only by detecting the peak of the correlation in the multidimensional space.
The light diffusion in the strong scatterer was simulated like the human skin. It was possible that the technique reported carried out Monte Carlo simulation to which also newly took in spectroscopic information. The skin was irradiated with the ultraviolet ray, and spectral data of the post-irradiation were acquired, and the change of melanin and hemoglobin was measured. The experiment in which the ultraviolet ray quantity changed was carried out, and the result was analyzed.
The technique which estimated the visual performance after the injection from the pigmentary color before it injects the human skin to the hypodermic on gelatine model and collected actually was examined, and the clinical application was tried.
