Light equalizing system of laser illuminator

激光照明器的均光系统

Abstract

The invention relates to a light equalizing system of a laser illuminator and belongs to the field of laser illumination. According to the light equalizing system, one side of a polygonal mirror body is contacted with one end of a motor; laser illuminators are respectively arranged at the two sides of the polygonal mirror body; and a lens is arranged below the polygonal mirror body. The light equalizing system of the laser illuminator has the beneficial effects that laser light spots projected on the polygonal mirror body are rotated at a constant speed; and after the laser light spots are overlapped by the lens, light energy accepted by the light spots on each region of an overlapped surface is equal and uniform, so that the influences on the light spots by multi-transverse-mode properties of a laser device can be effectively eliminated and the light spots are equalized.
本发明涉及一种激光照明器的均光系统,属于激光照明领域。多面镜体的一侧与电机的一端接触,所述多面镜体的两侧分别设置激光照明器,透镜设置在多面镜体的下方。有益效果在于:投射在多面镜体上的激光光斑产生匀速转动,经透镜叠加后,使光斑在叠加面上每一区域所接受的光能量是相等且均匀的,这样就有效地消除了激光器的多横模特性对光斑的影响,使光斑均化。
