With the continuous development of industrialization, advanced equipment is being applied in an increasingly wider range of fields, gradually replacing manual labor. New technologies and new equipment are constantly being put into practice. In the past, due to the limitations of factors such as technological level and price, the application of digital laser distance meter was restricted. However, the situation is different now. Many industries have put forward new requirements for the comprehensive performance of laser distance meter, and its application scope has significantly expanded.
The measurement scope of digital laser distance meter ranges from several meters to several kilometers, and users can flexibly choose according to specific situations. For example, in general indoor measurement work, the distance requirement is not high, but the precision requirement is extremely strict. At this time, a 632nm handheld laser distance meter is usually used. If the measurement distance is relatively long, a 905nm telescope laser distance meter is generally adopted, and its measurement range is generally between 5 and 3000 meters. This kind of laser distance meter is mainly used in outdoor surveying and mapping, power communication, port terminals, golf, hunting and other fields. If you want to measure a farther target, such as a target at a distance of 3 to 20 kilometers, you need another type of laser distance meter, such as an infrared long-distance digital meter with wavelengths of 1064nm/1535nm/1550nm. This requires extremely high precision in the production of various components, so the unit price is relatively expensive.
At the same time, digital laser distance meter is widely used in the fields of architectural measurement and automation that require strong light. If there is light pollution in the measurement environment, it will affect the measurement accuracy.
With the rapid development of high-tech technologies such as electronic technology, laser technology, and optical technology, it provides an important foundation for the improvement of long-range laser distance meters. Especially, emerging disciplines represented by laser applications have emerged. The innovation of relevant concepts and rich practical experience provide an effective reference for the research of long-range laser ranging technology.
