Abstract

The design and fabrication of several single-element laser-beam projectors are described. These projectors take a Gaussian laser beam and expand it into a uniform intensity diverging shape, which can be either a single line, circle, cross, star, or a D. Each element consists of a single segmented surface designed so as to produce the required projected shape.

摘要

本文描述了几种单元素激光束投影仪的设计与制造。这些投影仪接收高斯激光束并将其扩展为强度均匀的发散形状，该形状可以是单线、圆形、十字形、星形或字母D。每个元件都由单个分段表面组成，其设计目的是产生所需的投影形状。
