| Outline of Final Research Achievements |
This project aimed at developing the technology to analyze a variety of characteristics of fluorescent objects, such as the bispectral characteristic, the bidirectional characteristic, the appearance characteristic, and the interreflection characteristic.
First, we constructed a bispectrometer system for precise measurement of the bispectral characteristics of fluorescent objects, and a spectral imaging system using a camera and a LCT filter. Second, we developed a method to estimate the bispectral Donaldson matrices of fluorescent objects using two illuminant projections with continuous spectral-power distributions. Third, a method was proposed for measurement and modeling of bidirectional characteristics of fluorescent objects. Fourth, we evaluated appearance of fluorescent color based on visual experiment and analyzed the appearance difference from object color. Finally, we studied the interreflection phenomenon observed from closely apposed fluorescent objects.
