Application of Line Laser in Constructing Optical Mirror Testing Path

基于激光标线仪能够非接触式输出连续参考基准的特性,提出将激光标线仪应用于辅助构建光学镜面测试光路,分别研究了激光标线仪在平面镜测试、球面镜测试、Ritchey-Common法测试、非球面镜测试等测试光路构建中的作用以及在光路调整中的操作事项,总结了激光标线仪在空间定位、光轴校正中的特殊优势,讨论了激光标线仪误差对于测试的影响以及相应的修正措施,并通过实验比对验证了激光标线仪相比传统辅助测试设备的优势。研究表明用激光标线仪能替代传统的辅助对准调试设备和方法,对于不同类型的光学镜面测试均有很好的适应性。

To investigate the application of line laser in the construction of the optical testing path which based on its ability to no-contract output continuous reference datum,the assistant role of the line laser in testing different types of mirrors has been studied,such as plane mirror testing,spherical mirror testing,Ritchey-Common testing,aspheric mirror testing etc,and the operational guidance in the adjustment has been proposed,that scientifically and systematically demonstrate its special advantages in spatial position and optical axis correction,also the interference of its error to the testing and the corresponding correction measures has been discussed,then verified the advantages by experimental comparison with the traditional equipment.The results show that the line laser can replace the traditional auxiliary alignment equipment and methods,and it has good adaptability for different types of optical mirror testing.
