The Rotating Laser

A rotating laser works by emitting a laser beam while spinning at up to 1,000rpm, essentially emitting a solid plane of light. Each time the beam sweeps by, targets mounted anywhere along the beam sense the position of the light to within 0.001 of an inch, recording the exact location and thereby detecting any deviation.

In contrast to manual alignment, the use of a rotating laser is more accurate, faster and useful over greater distances. When combined with a central processing unit, using a rotating laser also allows for simultaneous measurement from up to 20 multiple targets, giving real-time feedback and electronic storage of the data collected.

Rotating lasers are typically used to measure squareness, flatness and straightness.
