我厂原仅有一台“ZYI”型光学自动准直仪(可测距离为5米)。我们曾用它完成了一次长导轨的测量任务(12米),并总结出了光学自动准直仪的“分段重叠测量法”,使测量范围较小的仪器发挥了较大的作用,具体方法如下:1.将仪器本体置于待测导轨一端。反光镜底座L=500毫米。由始逐段测起,每测量段长为500毫米。测至仪器可测的最大距离,作好每段的读数 My factory originally only one “ZYI” type optical automatic collimator (measurable distance of 5 meters). We have used it to complete a long rail measurement mission (12 meters), and summed up the optical autocollimator “piecewise overlap measurement method”, so that the measurement range of smaller instruments play a greater role, the specific The method is as follows: 1. Place the instrument body at one end of the guide rail. Mirror base L = 500 mm. Measured from the beginning by the paragraph, each measurement length of 500 mm. Measured to the maximum distance the instrument can measure, make each section of the reading
