摘要：
Colorimetric characters are very important to the optical engine, the kernel of the projector. The equations to calculate the colorimetric characters of the color wheel in optical engine are proposed. They are proven by measurements and the calculation results. Based on this theory, the sensitivity of the spectral transmittance of the color filters to the chromaticity coordinates is analyzed. A conclusion on the color filters of the color wheel which is useful to the tolerance control is drawn. Finally, a color wheel system is designed by using the theory. The design can satisfy the specific of the original color wheel well. (c) 2006 Elsevier GmbH. All rights reserved.
