Abstract
A spatial light modulator of the so-called deformable mirror device (DMD) type has an array of individual mirror ments (20) arranged in lines. The elements are individually driven to change their orientations. Portions (30) of the mirror ments are non-reflecting such as to divide the mirror elements into substantially equal portions forming a greater number of lines of narrower width, with a view to reducing the subjectively visible line structuring.
