Outline of Final Research Achievements

In order to contribute to imaging technology with remarkable progress, this research aims to develop a standard light source for luminance with high stability and luminance dynamic range control in the mega luminance range by utilizing microlenses and advanced optical element etc.
The construction of LED light source part in the standard light source was achieved, and optical modeling of the diffusing optics part in the standard light source was calculated and optimized with the ray tracing method. In addition, it was fabricated and evaluated for the standard light source. As a future research plan, with result of this recearch results,it is to complete the standard light source that can be used for providing of luminance standard.
