摘要：
A composite scanning unit for reducing speckle noise and a laser projection system employing the composite scanning unit are provided. The composite scanning unit includes a plurality of mirror surfaces disposed along a rotation axis, wherein at least two of the plurality of mirror surfaces sequentially scan diffraction beams having different orders on the screen.
