ABSTRACT:
The digital mirror device (DMD) is an array of single mirrors, which are deflectable on mirror deflection axes (MDAs, as e.g. characterized by their orientation with the array raster). In the state of the art, all single mirrors on a DMD have parallel MDAs. In our invention, the array is made of different classes of mirrors. These classes differ by the orientation of their MDAs. The invention relates to the simultaneous processing of different characteristics of light (e.g. color) by a single DMD-chip.
