Characteristics and application scope of laser rangefinder
A rangefinder is a tool for measuring length or distance. It can also be combined with an angle measurement device or module to measure angles, areas and other parameters. Rangefinders come in many forms, usually a long cylinder, consisting of an objective lens, an eyepiece, a display device (can be built-in), and a battery.
The accuracy of a laser rangefinder mainly depends on the accuracy of the instrument's calculation of the time between laser emission and reception. According to the technology used and application scenarios, laser rangefinders can be divided into conventional laser rangefinders with an accuracy of about 1 meter ( Mainly used for outdoor sports, hunting, etc.) and high-precision laser rangefinders used in surveying, land surveying, 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, able to measure long distances without reflectors and low reflectivity
2. There is a synchronization input terminal, which can measure multiple sensors simultaneously.
3. Wide measurement range and short response time
4. Compact appearance design, easy to install and operate
5. Can measure the distance of various objects (no reflector required)
6. Add a filter to measure high-temperature objects
7. Visible light is easy to aim at the object under test
Things to note when using the laser rangefinder: The laser rangefinder cannot be aimed at the human eye for direct measurement to prevent damage to the human body. At the same time, general laser rangefinders are not waterproof, so you need to pay attention to waterproofing.
Laser rangefinders have been widely used in the following fields: electricity, water conservancy, communications, environment, construction, geology, police, fire protection, demolition, navigation, railways, anti-terrorism/military, agriculture, forestry, real estate, leisure/outdoor sports, etc. .
