Scanning Measurement of Coated Glass Color-Difference and Design of Anti-Interference

Abstract:

Based on the colorimetric theory and combined with the production process of glass industry, a color-difference measurement system was designed. The system was applied to online color-difference detection for coated glass. Scanning measurement of color-difference based on spectroscopy was detailed, and the technologies of light source modulation and signal demodulation synchronization were introduced into the system. This avoided using sensor masks or soft curtain to eliminate backlight interference. Under the light source with fluctuations and other background noise, the new system can get robust measurement values. The experimental results show that the anti-interference method smooths the curve of color-difference, and improves the signal-to-noise ratio. The system meets the demands of practical color-difference testing, and provides a new method for online color measurement with high accuracy.
