Zusammenfassung:Systems and methods are utilized for performing geometric multiplexing in MEMS display systems that utilize RGB laser diodes and MEMS mirrors to compensate for angular separation between the RGB light that results from passing the RGB light emitted from the RGB laser diodes through a single collimating lens shared by the RGB laser diodes, as opposed to utilizing a separate collimating lens for each corresponding laser diode. Spatial offsets between the RGB light at the target display, resulting from the angular separation, are compensated for by applying temporal buffers to the pulsing of the RGB laser sources so that the RGB light is horizontally and vertically aligned at the appropriate pixels of the target display during scanning by the MEMS mirrors system.
