Basic Knowledge About Laser Range Finder

Through time, people from all around the world had to come up with different ways of measuring length from one point to another. A few years back, one of the largest breakthroughs in this industry came forward, as the first laser range finder was built. This device is basically a rangefinder that works by using laser in order to determine the distance to a certain object.

Operation Principle Of Electronic Rangefinder

When it comes down to how laser range finders work, most of them function by the principle of pointing and sending a laser beam at an object and then measuring the time that it takes for the pulse to be reflected from the target and come back to the device. While these devices definitely aren’t the most accurate ones due to the fact that they can’t do sub-millimeter measurements, they can still be considered extremely accurate, especially for what they are normally used for. With this factor in mind, the actual precision of a laser range finder is determined by the fall or rise time of the laser pulse sent together with the speed of the receiver. Because of this, those who use sharp laser pulses that also have fast receivers can definitely get more accurate results when compared to those who don’t.

An interesting thing about laser rangefinders is the fact that despite of the fact that the laser beam is actually quite narrow and it eventually spreads, most of these can target and measure incredibly long distances accurately. Most go from around 400 yards up to 27000 yards, which is great range to put it straight. However, many wonder what stops the beam from being less accurate as targets are further. Well, this mostly happens due to the fact that different effects are present throughout the air which can cause oscillations in the laser beam. The further it travels, the more distorted it gets and this is one of the main reasons why commercial laser rangefinders aren’t able to measure distances 27000 yards away whereas a military laser range finder can, as they have a much powerful laser beam and faster receivers.


For those who are not aware, laser rangefinders can be used for a high number of purposes. To start off, measuring distances is something done a lot in the military, especially by snipers and artillery. Additionally, these devices are also very popular with hunters, as many of them need to measure distances in order to get an accurate shot. It is also worth mentioning that laser range finders are also used in other applications, such as forestry, 3D modeling, sports and industrial processes, thus ensuring their great popularity with people from all around the world.

All in all, these are powerful devices that can measure distances accurately and can also be used in a wide variety of processes. Thanks to the fact that they do not represent a threat to our eyes and to the simple idea that thousands of people use them on a daily basis, it can be safely said that laser rangefinders are truly an innovation.
