摘要
针对目前传统光学水准仪的i角不稳定对测量结果造成的影响,在研究和分析了水准仪误差源的基础上,根据液体自由表面在重力场作用下始终保持水平的原理,开发了悬浮平台激光水准仪。该仪器无论向哪个方向倾斜,都能保持测量光束水平,提高了水准仪的稳定性和测量精度。
Aiming at the influence of measurement results caused by the traditional optical level i angel, this paper with analysis and study on the level error source introduces the development of a suspension platform laser leveling instrument based on the principle of liquid＇ s free surface keeping horizontal under the action of gravity. No matter which direction it leans to, the instrument maintains the measuring beam horizontal. Therefore, the stability and accuracy will be improved a lot.
