Abstract
A phase calibration method includes: producing a synchronization signal; controlling switches of a light source based on a time series; measuring a first light intensity of the light passing through a phosphor wheel and a color wheel; changing phases of the phosphor wheel or the color wheel; measuring a second light intensity of the light passing through the phosphor wheel and the color wheel; changing the phases of the phosphor wheel or the color wheel again; measuring a third light intensity of the light passing through the phosphor wheel and the color wheel; repeating changing the phases if the second light intensity is greater than the first light intensity, and the third light intensity is greater than the second light intensity; or when the second light intensity is smaller than the first light intensity, and the third light intensity is greater than the first light intensity.
