The laser rangefinder has what features?
The laser range finder uses the pulse method to measure the distance. The biggest feature of this type of range finder 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, fire protection, blasting, navigation, railways, agriculture, forestry, real estate, Leisure, outdoor sports, lifesaving, surveying, engineering, hunting, etc.

The laser range finder has the characteristics of good linearity, small divergence angle, and concentrated energy. When the laser is used for distance measurement, it is usually divided into different types according to the length of distance measurement and the principle of distance measurement. There are usually three types of measurement principles: pulse method, phase method, and trigonometric method. Different measurement methods have different fields of application.
The pulse method (including the time-of-flight method) emits a laser pulse from the laser source, and when the laser pulse encounters an object, it is reflected to the source. Measure the time interval between the laser emission moment and the receiving moment, and then divide it by the light beam to calculate the distance from the starting point to the target; the phase method emits a continuous pulse wave from the emission source, and calculates the phase difference between the emission wave and the reception wave. Distance; Trigonometry A beam of laser light is emitted from the source, and the laser light is reflected to the receiver after encountering the target. The transmitting point, the target object, and the receiving point form a triangle, and the distance from the instrument to the target can be measured by measuring the angle of the triangle.
Scope of application: The pulse method is usually used for long-distance and large-range measurement, the measurement distance is from hundreds of meters to several kilometers, the measurement accuracy is usually centimeters to decimeters, 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-range measurements, 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 humanized design. Through the built-in monocular, it is convenient and intuitive to search for targets and measure intuitively. 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 will definitely be results within 2 seconds. At the same time, it also has multiple modes such as rainy days and foggy days to adapt to various usage environments. And it is very novel and pocket-sized, which naturally becomes the best helper for various outdoor activities.
