A new laser grating scanner concept with attractive capabilities is described. The grating used in this scanner is a computer-generated hologram. The constructional parameters of this type of computer-generated hologram are discussed. In addition to achieving a laser beam deflection, the computer-generated hologram can correct the curvature of the scanning beam. Experiments demonstrating the feasibility of this type of scanner in a drum and disk configuration are presented. Realization of two-dimensional scan patterns using computer-generated holograms is illustrated by experimental results.
描述了一种具有吸引人功能的新型激光光栅扫描仪概念。该扫描仪中使用的光栅是计算机生成的全息图。讨论了这种类型的计算机生成全息图的结构参数。除了实现激光束偏转外，计算机生成的全息图还可以校正扫描光束的曲率。给出了在鼓形和盘形配置中证明这种类型扫描仪可行性的实验。实验结果说明了使用计算机生成全息图实现二维扫描图案的情况。
