摘要： A laser alignment device (1) provides horizontal and vertical reference planes, lines, and points. The alignment device includes a pendulum assembly that supports a laser beam source assembly (30), two reflectors, and two motors (42, 44). The laser beam source directs beams onto the reflectors -producing a horizontal reference beam and a vertical reference beam. Each reflector is rotated by one of the motors. Continuous rotation generates a reference plane; dithering generates a reference line, and no movement results in a reference point. The pendulum assembly (20) includes a coarse pendulum (26) and a fine pendulum (28). The coarse pendulum roughly levels the alignment device. The fine pendulum (28) supports the laser beam source assembly and brings the alignment device to a level position. The laser alignment device also includes a motor control system that enables users to accurately position the device's references.
