ABSTRACT:
The 2-channel display system with micro electromechanical systems (MEMS, e.g. DMDs from Texas Instruments) simultaneously generates a right and a left image in two discrete modulation channels, which differ by the polarization of their light beams. More specifically, the invention relates to the chirality (handedness) of MEMS and the geometric problems associated with this handedness in superposition systems. In this application we uncover a solution to superpose the images modulated by identical MEMSs which have their mirror deflection axes oriented parallel to an axis of symmetry of the image raster of the MEMSs.
