Shearing radiation beam for imaging printing media
Abstract:
An illuminator (10) for producing a radiation spot (120) on a workpiece (110) comprises a laser light source (20) and a beam-shearing optical system (30). Fine structure (160) generated by an integrator (80) of laser light source (20) in integrated beams (90) as a result of path length differences among coherent light beams (70) from emitters (60) of lasers (40) is sheared by the inclusion of beam-shearing optical system (30) into illuminator (10). Beam-shearing optical system (30) allows illuminator (10) to produce a radiation spot (120) in which the fine structure (160) is spread so that scanning of radiation spot (120) does not produce the striations (140) in scanned patch (170) that are obtained with prior art illuminators.
Abstract(Chinese):

用于在工件（110）上产生辐射点（120）的照明器（10）包括激光光源（20）和光束剪切光学系统（30）。 作为来自激光器（40）的发射器（60）的相干光束（70）之间的路径长度差的结果，由集成光束（90）中的激光光源（20）的积分器（80）产生的精细结构（160） 通过将束剪切光学系统（30）包括在照明器（10）中来剪切。 光束剪切光学系统（30）允许照明器（10）产生辐射光斑（120），其中精细结构（160）被扩展，使得辐射光斑（120）的扫描不会产生扫描的条纹（140） 贴片（170），它们是用现有技术的照明器获得的。
