| Abstract: | A new device for measuring color of automobile lamp is presented. It is based on the theory of chromaticity and the method of spectrum reflection. A CCD is used as a photodetector to receive electric signal corresponding to spectrum of automobile lamp. A fast spectrum analysis is realized and a way of spectrum analysis on color of automobile lamp is given. Data processing with VB by computer is used and data acquisition program phase is showed. Using this system, comparing test value of standard color card with standard value of its, the error of , is less then 0.01. |
