Abstract: A laser beam alignment system includes a trans­mitter (1) which establishes a laser reference plane by continuously rotating a horizontal laser beam about the transmitter. A remotely located receiver (5) senses the elevation of the laser reference plane and reflects a portion of the laser energy back to the transmitter (1) where the reflected energy is employed to produce a signal indicative of the range of the receiver (5) and its location with respect to a reference axis. The position of the receiver is thus established in three dimensions.

Abstract translation: 激光束对准系统包括发射器（1），其通过围绕发射器连续旋转水平激光束来建立激光参考平面。 远程定位的接收器（5）感测激光参考平面的高度并将一部分激光能量反射回发射机（1），其中采用反射能量来产生指示接收机（5）的范围的信号， 及其相对于参考轴的位置。 因此，接收机的位置在三维中确立。
