1. An image generation system, comprising:

  • an optical fiber positioned to receive a source beam from a coherent optical source;

    a ditherer being coupled with the optical fiber and operable to modulate a position of at least a portion of the optical fiber;

    a lens configured to refract the source beam, such that the source beam is aimed at a microlens diffuser;

    the microlens diffuser being positioned to project the source beam onto a spatial modulator; and

    the spatial modulator positioned to project the source beam via an imaging lens, to a target.
