Description

一种用于激光测量头部的出入光旋转组合机构In and out light rotation combined mechanism for laser measuring head 技术领域Technical field
本发明涉及出入光旋转组合机构，尤其涉及一种用于激光测量头部的出入光旋转组合机构。The invention relates to an entrance and exit light rotating combined mechanism, in particular to an ingress and exit light rotating combined mechanism for a laser measuring head.
背景技术Background technique
激光干涉仪在使用的过程中，必须调光来保证激光干涉仪和运动轴线两者准直；此时激光干涉仪、线性干涉镜、参考反射镜、线性反射镜，结合调节机构、运动机构来回多次调节保证两者准直，准直后方可用激光干涉仪进行测量校准；由于调节准直时要求参考反射镜光斑和线性反射镜光斑重合在一起，光斑的大小会影响光斑重合判断，另外还需要借助光闸来判断，出射光的光束越小越容易判断两组反射光的偏差；然而测量校准时有时又需要大光斑，所以要求调节准直时使用小光斑快速、方便，测量时大、小光斑可以切换使用来测量线性距离的长短，另外光闸还能随时切换，目前现有的激光干涉仪光路调节结构中未能实现将以上全部功能组合在一起；During the use of the laser interferometer, it must be dimmed to ensure that the laser interferometer and the motion axis are collimated; at this time, the laser interferometer, linear interferometer, reference mirror, linear mirror, combined with the adjustment mechanism and the motion mechanism Multiple adjustments ensure that the two are collimated. The laser interferometer can be used for measurement and calibration after collimation. Since the reference mirror spot and the linear mirror spot are required to coincide when adjusting the collimation, the size of the spot will affect the spot coincidence judgment. It is necessary to use the shutter to judge that the smaller the beam of the outgoing light, the easier it is to judge the deviation of the reflected light of the two groups; however, sometimes the large spot is needed when measuring and calibrating, so it is required to use the small spot to adjust the collimation quickly and conveniently, and the measurement time is large. Small spots can be switched to measure the length of the linear distance, and the shutter can be switched at any time. At present, the existing laser interferometer optical path adjustment structure fails to combine all the above functions;
现有方案一，如图1所示,现有的激光干涉仪光路调节结构包括光闸101、出光孔102、出光孔103、入光孔104，这种出射光、入射光、光闸101虽然能够做到一起调节准直和测量校准，但是这种方式存在缺陷，出射光斑不能改变直径大小，只能一种直径的光斑，不能做到小光斑调节准直，及大小光斑任意组合测量校准，组合方式单一，调节效率低，影响使用；In the prior art, as shown in FIG. 1 , the optical path adjusting structure of the prior art laser interferometer includes a shutter 101, a light exit hole 102, a light exit hole 103, and a light entrance hole 104. The light, the incident light, and the shutter 101 are formed. Can adjust the collimation and measurement calibration together, but this method has defects, the exit spot can not change the diameter, only one diameter of the spot, can not achieve small spot adjustment collimation, and the size of the spot can be arbitrarily combined measurement calibration, The combination method is single, the adjustment efficiency is low, and the use is affected;
现有的方案二，如图2所示，现有的激光干涉仪光路调节结构包括出光头201、光闸202、出光孔203、入光孔204、光闸出光孔205和光闸206，，这种方式是只有出射光、入射光两个光孔，光闸206是另外辅助增加，不是一体式，而且和图1一样存在相同的缺陷，出射光孔直径大小只有一种，不能做到小光斑调准直，大小光斑任意组合测量校准；操作繁琐、调节效率低，不是最佳的方案。In the existing solution 2, as shown in FIG. 2, the optical path adjusting structure of the existing laser interferometer includes an optical head 201, a shutter 202, a light exit hole 203, a light entrance hole 204, a shutter light exit hole 205, and a shutter 206. The way is that there are only two light holes for the outgoing light and the incident light. The shutter 206 is additionally assisted to increase, not integrated, and has the same defects as the one shown in Fig. 1. The diameter of the exiting optical hole is only one kind, and the small spot cannot be achieved. Adjust the alignment, the size of the spot can be measured and calibrated in any combination; the operation is cumbersome and the adjustment efficiency is low, which is not the best solution.
