Abstract: A composite scanning unit and a laser projection system having the same are provided to decrease a speckle noise by forming non-correlated speckle patterns. A line optical modulator(130) of a composite scanning unit(200) modulates light from a laser source(110) corresponding to image information and forms a line panel. A projection lens unit(170) projects the line panel on a screen. Plural mirror surfaces are arranged between the projection lens unit and the screen and are rotated to scan the line panel on the screen. The mirror surfaces are arranged along a rotation axis. At least two mirror surfaces of the mirror surfaces sequentially scan beams with different diffraction orders on the screen.
