IMPROVED REAL-TIME GONIOSPECTROPHOTOMETER FOR ECONOMICALLY AND QUICKLY OBTAINING EACH DEPENDENCE OF COLOR SPECTRUM BY USING SAMPLE MATERIALS OR LIGHT SOURCE

摘要

PURPOSE: An improved real-time goniospectrophotometer is provided to economically and quickly obtain each dependence of a color spectrum by using sample materials or a light source. CONSTITUTION: An improved real-time goniospectrophotometer parabola-irradiates light from a light source in order to provide light beam from an azimuth angle within a zenith angle. Light is spectrum jet from the beam. An angular spectrum is obtained correspondingly to the zenith angle. The light beam includes a discrete beam set. Each beam included in the discrete beam set corresponds to the zenith angle within the zenith angle. The discrete beam set is collimated. Spectrum distribution of light from the light beam refers to diffraction of the light beam in a diffraction lattice.
