Meanwhile, the way advanced previously that the collimation beam of light acts as measuring basis and the four-quadrant photocell as receiver is not applied practically. Moreover, laser interferometer is too expensive to be extended.
传统的直线度检测方法,如平尺法、水平仪、钢丝法等,虽然检测器具简单,实际中常被采用,但各自都存在一定的局限性,测量精度不高,效率低,性能无法保证;与此同时,以准直光束为测量基准,四象限光电池为接收器件的方法由于种种原因一直未能实用化,而激光干涉仪测量法则由于其价格过高,而难以得到推广。
