ABSTRACT:
A method of generating a color wheel index signal for use in a display system (10) that uses a spatial light modulator (14) and a color wheel (15). The index signal is compared to a reference signal associated with an input image signal so that the color wheel and the data being displayed can be synchronized (FIG. 2). The index signal is generated by placing a color-sensitive photodetector (14a) in close proximity to the spatial light modulator (14). Light filtered through the color wheel (15) illuminates both the spatial light modulator (14) and the photodetector (14a). The photodetector (14a) responds to color transitions in the filtered light, generating a pulse in response to each transition to the color to which it is sensitive.
