<p><P>PROBLEM TO BE SOLVED: To provide a laser-light-source device whereby in an apparatus for reducing the speckle noise of an illumination using a laser light, the speckle-noise pattern of the laser light can be removed effectively therefrom, without loss in the optical system of the apparatus and without structural components. <P>SOLUTION: The laser-light-source device includes a laser light source for emitting a laser light, a deflecting element disposed on the optical axis of the laser light to deflect the travelling direction of the laser light by changing its refractive force, a rod lens for making the emitted light from the deflecting element uniform, and a projecting lens for projecting the outputted light from the rod lens onto a projecting plane. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
