What is laser distance meter

Laser distance meter is an instrument that measures the distance of the target by modulating a certain parameter of the laser. The measuring range of laser rangefinder is 3.5 ~ 5000 meters.

Laser rangefinder has the advantages of light weight, small volume, simple operation, fast and accurate speed, and its error is only one fifth to one hundreds of other optical rangefinders.

LaserWorks was established in 2011, specialized in pulse OEM, ODM laser rangefinders,rangefinder modules,for golf,hunting,UAV etc. applications.

LaserWorks Provide Laser Rangefinder, Range Finder, Golf Rangefinder, Laser Distance Meter, Distance Finder, etc.

Till now, LaserWorks has become the company with independent development, production, quality control, sales & after-sale service.

According to the ranging method, it is divided into phase method rangefinder and pulse method rangefinder. The pulse laser rangefinder emits a beam or a sequence of short pulse laser beams to the target during operation, and the laser beam reflected by the target is received by the photoelectric element. The timer measures the time from emission to reception of the laser beam, and calculates the distance from the observer to the target. The phase method laser rangefinder detects the distance by detecting the phase difference between the transmitted light and the reflected light when they propagate in space.

Frequently Asked Question

Do you have any question?

What is the principle of laser distance meter?

Laser distance meter is an instrument that accurately measures the distance of the target by using a certain parameter of the modulated laser. The ranging principle can be basically reduced to measuring the time required for light to and from the target, and then calculate the distance d through the light speed c = 299792458m / s and the atmospheric refractive index n. Because it is difficult to measure the time directly, it is usually to measure the phase of continuous wave, which is called phase measuring rangefinder. Of course, there are also pulse rangefinders. Usually, precision ranging requires the cooperation of total reflection prism, while the range finder used for house measurement is directly measured by the reflection of smooth wall, mainly because the distance is relatively close and the signal intensity reflected by light is large enough. From this, we can know that it must be vertical, otherwise the return signal is too weak to get the accurate distance.

What is a laser rangefinder?

Laser rangefinder is an instrument that uses laser to accurately measure the distance of the target. When the laser rangefinder works, it emits a very thin laser beam to the target, and the photoelectric element receives the laser beam reflected by the target. The timer measures the time from the emission to the reception of the laser beam, and calculates the distance from the observer to the target. The laser rangefinder has the advantages of light weight, small volume, simple operation, fast and accurate speed, and its error is only one fifth to one hundredth of that of other optical rangefinders.
