UNPOLARIZED LIGHT LASER LIGHT SOURCE DEVICE AND A PROJECTOR, CAPABLE OF REDUCING A SPECKLE BECAUSE AN INTERFERENCE OF THE COLOR IS REDUCED BY USING A POLARIZER SHAFT OF A LIGHT SOURCE ARRANGED TO BE PLURAL

摘要

PURPOSE: An unpolarized light laser light source device and a projector is provided to prevent a deformation of color caused by an angle difference of a polarizer shaft while watching a 3D image and to protect eyes because a directivity of the light is decreased.;CONSTITUTION: An unpolarized light laser light source device comprised of laser diodes and color mixing unit. Each laser diode is arranged to have two or more angels of a polarizer shaft of outputted light. The color mixing unit is arranged on a light path of a plurality of laser diodes. The color mixing unit composes a plurality of lights into a composite light beam. The composite light beam output from the color mixing unit comprises two or more polarizer shafts. The adjacent laser diode are arranged to have 15 degree of angle distance each other.;COPYRIGHT KIPO 2012
