What are the characteristics of the laser rangefinder?
The laser rangefinder uses the pulse method to measure the distance. The biggest feature of this type of rangefinder is its high accuracy (the accuracy is generally around +/- 1 meter). Laser rangefinders have changed the way people measure distances and have been widely used in the following fields: electricity, water conservancy, communications, environment, construction, geology, police, firefighting, blasting, navigation, railways, agriculture, forestry, real estate, Leisure, outdoor sports, lifesaving, surveying, engineering, hunting, etc.

The laser rangefinder has the characteristics of good linearity, small divergence angle and concentrated energy. When the laser is used for ranging, it is usually divided into different types according to the length of the ranging and the principle of ranging. From the measurement principle, it is usually divided into three types: pulse method, phase method, and trigonometric method. Different measurement methods have different fields of application.
In the pulse method (including the time-of-flight method), a laser pulse is emitted by a laser source, and when the laser pulse encounters an object, it is reflected to the source. The distance between the starting point and the target can be calculated by measuring the time interval between the laser emission time and the receiving time, and dividing it by the beam; in the phase method, the continuous pulse wave is emitted by the emission source, and the phase difference between the emitted wave and the received wave is calculated to calculate Distance; trigonometry The source emits a laser beam, and the laser beam is reflected to the receiving end after encountering the target. The transmitting point, the target and the receiving point form a triangle. By measuring the angle of the triangle, the distance from the instrument to the target can be measured.
Scope of application: The pulse method is usually used for long-distance and large-range measurement, the measurement distance is from several hundred meters to several kilometers, the measurement accuracy is usually in centimeter-decimeter, and the measurement time is short.
The phase method is usually used for close-range measurement, the measurement distance is from tens of centimeters to tens of meters, the measurement accuracy is usually up to millimeters, and the measurement time is relatively long.
Trigonometry is usually used for very close measurement, the measurement distance is usually tens of millimeters, the measurement accuracy can reach the micron level, and the measurement time is very short.
This series of products continues the user-friendly design. Through the built-in monocular, you can easily and intuitively search for targets and intuitively measure. What you see is what you get. All measurement information is displayed in the field of view of the telescope, and the measurement speed is very fast. 1- There must be results within 2 seconds, and at the same time, there are various modes such as rainy days, foggy days, etc., which are suitable for various use environments. And it is very novel and pocket-sized, which naturally becomes the best helper for all kinds of outdoor activities.
