| Summary: | 碩士 === 國立中央大學 === 光電科學研究所碩士在職專班 === 97 === The purpose of color measuring instrument is judging the colorinformation by scientific method, which may instead of the human’s eyes.Generally, the instruments of color measuring can be divided intospectrophotometer and color meter. The former may use prism or gratingto separate the light to transmit to a receiver, this could achieve highaccuracy but with a higher price. The latter mean the straight tristimulusfrom color filter, however there is no spectrum information with it.
In this thesis we establish a color measuring system was developed with three sensors, which can acquire the color spectral reflectance. Then we can use the specific algorithm to correct the average inaccuracy ΔEab amount 31.2398 down to 0.8431, and reconstruct the spectrum
information.
