Abstract
A system comprises a spatial light modulator comprising a plurality of modulation elements, the spatial light modulator operable to receive an optical signal comprising one or more optical channels, wherein the elements are operable to perform an optical function on at least one of the one or more optical channels. The system further comprises two or more reset groups associated with the spatial light modulator, wherein each reset group comprises one or more elements, and wherein at least one of the one or more optical channels resides on at least two of the two or more reset groups. The system also comprises a controller operable to actuate the elements of at least one of the at least two reset groups associated with the optical channel at a different time than any one or more other reset group of the at least two reset groups.
