Outline of Final Research Achievements

If a chemical concentrate within some particles like a soil would be predicted by using a light reluctance spectra analysis, the observed energies are contained both a direct-reflected light energy and a diffused light energy, and the ratio between direct-reflected and diffused light energy is not a constant value and it is unstable. A prediction accuracy of a chemical concentrate is tried to be improved using a characteristic of a polarized light reluctance rule. A direct-reflected light energy and a diffused light energy are able to predict by changing a reflection angle. In this study, a new measurement method was introduced that a layout of the lighting devices is not changing by a time, but the light energies of some layouts are measured at one observation. The ratio of direct-reflected and diffused light energies is predictable by a simulation and the values of the simulation and measurement did not have a contradiction.
