摘要
利用红外拍波干涉仪验证了用于无导轨大长度测量的3.39μm波段双线He-Ne激光两级合成波长组成方案。文中介绍了该合成成长组成方案的具体内容和用来验证该方案的红外拍波干涉仪工作原理,分析了所取得的实验结果。本工作为使用3.39μm波段双线He-Ne激光的大长度测量方案提供了实验依据。
The two-level synthetic wavelength formed scheme of 3.39 μm band dual -line He-Ne laser for large length interferometry without carriage guideway is tested and verified by using infrared beat wave interferometer. The concrete contents of this synthetic wavelength scheme and the principle of the infrared beat wave interferometer are presented. The experimental data are given and analyzed. This work provides experimental basis for the large length measurement scheme employing 3.39 μm dual-line He-Ne laser.
