红外激光光组中模拟指示的设计

A design for the simulative indicator in infrared laser system

本文提出了一种简单而实用的光学设计,解决了红外激光光路中使用可见光模拟指示的问题.同国内外有关的方案相比较,采用环形透镜的设计具有光组结构简单、使用直观、效能良好的特点.所得结果不但可以应用于CO_2激光治疗机(或激光刀),也可能应用于各种红外激光机械装置.文中还描述了这种设计的一个实际光学系统.

A simple practical optical design is prefered, and it is solved effectively to make use of simulative indication with visible light in infrared laser system. As Compared with the relative plan at home and abroad, adopting the design with ring lens has particular feature of simple structure, visual employment and good efficiency. The result obtained not only may apply to CO_2 laser treatment apparatus (or laser scalpel), but also it is possible to be applied to various machi nes of infrared laser. A real optical system of this design is described also.
