Rotating Laser Systems

The principle of rotating laser alignment is simple. A rotating laser, spinning at up to 1,000 rotations per minute, creates a solid plane of light that serves as a measurement reference. While typically leveled to gravity, the rotating laser can be mounted vertically as well as horizontally, or anywhere in between. Next, a rotating-laser target, mounted to the measurement tool, senses the position of the laser light within 0.001 of an inch each time the laser sweeps by. Multiple targets can be mounted at different points along the laser path. Lastly, data from the target(s) is fed to a central processing unit which displays the position information in real time. When multiple targets are used, data from all targets is typically fed to a laptop computer for simultaneous display, comparison and analysis.
