Laser Distance Measure

The science behind laser measurement devices is simple for every builder to understand. Many builders feel they are too busy keeping projects on schedule to worry about the subtle workings of laser beams. Every distance meter and magnetic locator uses the same fundamental principles to calculate distances from distant objects.

Delve Into the Science of Laser Measurement Devices

Every laser measurement device starts to measure distances by sending out light waves toward designated targets. While some devices feature a 180-degree arc that cuts down on errant signals, many lasers are built with 360-degree capabilities to accommodate measurements from multiple readers.

The majority of the light waves emitted by the head assembly dissipate with hitting magnetic targets and readers. The remaining waves strike the reader and bounce back to the laser head within fractions of a second. The distance between the head assembly and reader is determined by the amount of time it takes for the light wave to bounce back.

These scientific principles demonstrate the importance of an unobstructed space between the reader and the laser. Many excavators will try to station their lasers in a single spot for an entire project to maintain consistency in grade levels. The average excavator can spray spots in basement footings that are flush with the grade level, move the laser away from obstructions and set up again after calibrating levels based on painted spots.

Tiger Supplies sells magnetic locators, distance measurement readers and other products for builders around the United States. These supplies can be purchased without setting a foot in a store by looking at the Tiger Supplies website.
