ABSTRACT:
A spatial light modulator having a photo-detector for use in digital display systems is provided. The spatial light modulator modulates a light beam having multiple light components of different frequencies so as to produce color images. The photo-detector detects a component of the light beam and generates a timing signal. The timing signal is then used to synchronize the operation of the spatial light modulator with the sequence of incident light color components.
