<p>PURPOSE: A laser projection device is provided to remove the speckle of independent two laser beam by the speckle reduction element. CONSTITUTION: The laser light source projects the laser beam. The polarized light separator(20) separates the projected laser beam having the polarized light routes. The micro display panel(50) projects the video signal. The polarized light separator includes the complex semi transmission spreader including the optical transmission part and optical reflection part. The polarized light separator includes the wire grid polarizer(22). The polarized light separator includes quarter wave plate(24).</p> |
