How They Work |
Because the speed of light is constant, a pulse of laser light can be timed with exacting accuracy.The number of nanoseconds it takes an LDM to emit a light pulse to the surface being measured and receive the rebounded pulse is timed. The onboard computer does some quick math, and the computer then translates its result into a measurement of feet and inches. Indirect measuring, illustrated below, is an important feature that illustrates the LDM’s ability to shoot and compute. Rather than hoisting ladders, you shoot the tool’s laser at three points on the face of a building to determine its height. Next, press a key, and the onboard brain computes the calculations. |
Laser Distance Meters
Speed and accuracy aside, the question about laser distance meters now is how to put them to work.
