Title: Comparative Study on Two-Color and Three-Color Colorimetric Temperature Measurement Based on Colored CCD
Abstract: The two-color and three-color colorimetric temperature measurements are major methods of the coloredCCD-based radiation thermometry. The dynamic range and temperature measurement accuracy of the two-color andthree-color thermometry are analyzed and compared respectively. The theory analysis and experimental results showthat the two-color thermometry using red-green colors has much wider dynamic range than the three-color thermome-try in the combination of an aperture and shutter. In the other hand,the three-color thermometry has higher accura-cy than the two-color method when the radiator is assumed as a gray-body. Finally,the general temperature measure-ment platform flexibly switching the two-color and the three-color thermometry is proposed. The measurement plat-form combines the advantages of the two-color and three-color thermometry,which meets the requirements of widedynamic range and high measurement accuracy.
