| 1. A spatial optic modulating system with speckle reduction, comprising:
a spatial optic modulator, modulating and reflecting an image transferred in accordance with an upward or downward movement
of a ribbon which is operated according to a contraction or expansion of a piezoelectric element;
an image lens unit, transferring the image modulated from the spatial optic modulator as a diffraction image to a scanner;
and
a phase modulator, modulating a phase of the diffraction image transferred from the image lens unit.
