Compact multiple laser beam scanning module for high-resolution pico-projector applications using a fiber bundle combiner

We present a novel multiple laser beam scanning projection module using compact red-green-blue (RGB) fiber pigtailed laser modules for use in a high resolution pico-projector display system using a fiber bundle combiner in combination with a single MEMS mirror. This system can be used to create accurate multiple-projection images on a screen without overlaps or spaces among the projection images. The system uses very simple projection optics and has the potential to become a light engine unit for use in multiple projection systems, particularly those for light field displays. As such, light field display applications are also discussed.
