The Basics: What Is A Laser Distance Meter?
A laser distance meter is a tool for measuring distances, heights, and widths with high accuracy. It uses laser technology to determine the distance between two points by measuring the time it takes for a pulse of laser light to reflect off an object and return to the meter.
This information is then calculated and displayed on a screen in various units such as meters, feet or inches.
How Do Laser Distance Meters Work | The Technology Behind It
The laser distance meter works on the Time of Flight (TOF) measurement principle.
This means it measures the time a laser pulse takes to travel from the device to an object and back again. The meter emits a short burst of infrared light towards the target object, which is not visible to the human eye.
When this light hits the object, it reflects back to the meter, where a sensor detects it.
The time the light travels and returns is then measured and converted into a distance reading.
The speed of light is constant, meaning that the time it takes for light to travel and return can be accurately calculated.
Why Use A Laser Distance Meter?
Laser distance meters offer numerous advantages over traditional measuring tools such as tapes or rulers.
Some of these include:
Speed: Unlike manual measurements, which can be time-consuming and prone to errors, laser distance meters provide almost instantaneous readings.
Accuracy: With laser technology, distance measurements can be highly accurate, often within a few millimetres.
Ease of use: Laser distance meters are compact, lightweight and easy to operate. They also do not require physical contact with the object being measured, making them ideal for measuring hard-to-reach or hazardous areas.
