| Outline of Final Research Achievements |
We determined the optical properties (reduced scattering coefficient and
absorption coefficient) of apples in NIR region by time-of-flight spectroscopy. And we suggest to apply three-fiber-diffuse-reflectance spectroscopy (TFDRS), which detect the diffuse light intensity at couple of difference position from halogen light spot source, for the prediction of sugar content in apple without the use of chemometrics. It was shown that TFDRS can be used for the accurate prediction of apple, because the effect of light scattering in apple is not the significant. We applied Monte-carlo simulation using scattering and absorption coefficient decided to know the light propagation in apples and revealed that the transmission light intensity has the relation with the areal ratio of watercore.
