Abstract
In described examples, a spatial light modulator includes groups of pixels. Each group is arranged to transmit only a respective portion of a light spectrum. The respective portion has a respective dominant color. The respective portions of the light spectrum are distinct from one another, according to their respective dominant colors. Each group is controlled by a respective reset signal. The spatial light modulator is coupled to receive a selection from the integrated circuit and in response to the selection: cause a selected one of the groups to transmit its respective portion of the light spectrum; and cause an unselected one of the groups to block transmission of its respective portion of the light spectrum. A photodetector is coupled to: receive the respective portion of the light spectrum transmitted by the selected group; and output a signal indicating an intensity thereof.
