Abstract
The present invention describes a micro-mechanical light modulator including a two-dimensional array of modulating elements, in which small modulating elements are organized into larger modulating areas. Using smaller elements organized into larger areas increases the resonant frequency of the modulators and the modulation speed. In some implementations, multiple modulating elements are driven by shared signals, allowing the number of elements driven and the resulting area to increase without increasing the data traffic. In some implementations, an anamorphic optical path is used that leaves individual modulating elements of the micro-mechanical light modulator that are operated as a single area unresolved at an image plane of the workpiece being patterned. Devices and methods are described.
