A rangefinder is a tool for measuring length or distance, and can be combined with angle measuring equipment or modules to measure parameters such as angle and area. There are many forms of rangefinders, usually a long cylinder, which consists of an objective lens, an eyepiece, a display device (which can be built in), a battery and other parts.
The accuracy of the laser range finder mainly depends on the calculation accuracy of the time between the laser emission and the receiving of the instrument. According to the technology used and the application, the laser range finder can be divided into a conventional laser range finder with an accuracy of about 1 meter ( Mainly used for outdoor sports, hunting, etc.) and high-precision laser rangefinders used in surveying and mapping, land measurement, construction, engineering applications, military and other occasions that require high accuracy.
Laser ranging is a ranging method in light wave ranging. Generally, two methods are used to measure distance: pulse method and phase method.
Features:
1. Long-distance measurement, can measure long distances in the case of no reflector and low reflectivity
2. There is a synchronous input terminal, which can measure multiple sensors synchronously
3. Wide measurement range and short response time
4. Compact design, easy to install and easy to operate
5. It can measure the distance of various objects (without mirror)
6. Add a filter to measure the high temperature measured object
7. Visible light is easy to aim at the measured object
Problems that need to be paid attention to when using the laser rangefinder: The laser rangefinder cannot be directly measured at the human eye to prevent damage to the human body. At the same time, the general laser rangefinder is not waterproof, so you need to pay attention to waterproofing.
Laser rangefinders have been widely used in the following fields: electric power, water conservancy, communication, environment, construction, geology, police, fire protection, blasting, navigation, railway, anti-terrorism/military, agriculture, forestry, real estate, leisure/outdoor sports, etc. .
