Outline of Final Research Achievements

In the measurement of the spectral reflection characteristics of an object surface, a trade-off between the wavelength resolution and the measurement time becomes a problem. In this research, a high-speed spectral imaging system using a monochrome camera and a programmable light source was constructed to solve this problem. Moreover, a calibration method for the spectral distribution of illumination was established. By this calibration method, it becomes possible to use a camera spectral sensitivity is unknown in the spectral imaging system. In addition, the construction of a spectral image display system consists of the digital micromirror device and a programmable light source was tried, it aimed to develop the acquisition and display system of the spectral information.
