The features and potential applications of a laser range finder
The rangefinder is a tool for measuring length or distance, and can be combined with angle measuring equipment or modules to measure parameters such as angles and areas. There are many forms of rangefinder, usually a long cylinder, composed of objective lens, eyepiece, display device (can be built-in), battery and other parts.
The accuracy of the laser rangefinder mainly depends on the calculation accuracy of the time between laser emission and reception by the instrument. According to the technology and application used, the laser rangefinder 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 for surveying and mapping, land measurement, construction, engineering applications, military and other occasions that require high precision.
Laser ranging is a distance measuring method in light wave ranging. Generally, two methods are used to measure distance: pulse method and phase method.
Features:
1. Long-distance measurement, it can measure a long distance 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 operate
5. It can measure the distance of various objects (no mirror required)
6. Increase the filter to measure the high temperature measured object
7. Visible light is easy to align with the measured object
Problems that need to be paid attention to 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, 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: electricity, water conservancy, communications, environment, construction, geology, police, fire protection, blasting, navigation, railways, anti-terrorism/military, agriculture, forestry, real estate, leisure/outdoor sports, etc. .
