摘要
根据几何光学知识分析了激光标线原理.理论和实验表明:激光标线长度与激光光束形状、光学元件形状及材料折射率有关.并讨论了激光标线向两侧扩展的原因.
The principle of straight line laser is analyzed based on geometric optics theory. The theoretical and experimental results indicate that the length of the straight line formed by laser beam can be affected by many factors, such as the length of straight line laser, the shape of the laser beam, the shape of optical element, and the refractive index of the material. The reason of the line width broadening is also discussed.
