Laser range finder is widely used
With the rapid development of new technologies such as electronic technology and laser technology, the laser range finder was born in line with the times. A laser rangefinder is an instrument that uses a certain parameter of a modulated laser to measure the distance to a target. It is light in weight, small in size, easy to operate, fast and accurate, and its error is only one-fifth to several hundredths of other optical range finders.
Laser is a new technology developed in the 1960s. It is a kind of light with pure color, highly concentrated energy and good directionality. The application of laser technology to the range finder and the fusion of the two have achieved a major advancement in the range finder. The principle of its operation is very simple: the distance is measured by measuring the time from the start of the laser emission to the reflection of the laser light from the target. These advantages are concentrated in the laser range finder, making its market situation very good.
Now, laser rangefinders play a certain role in all walks of life, and are widely used in terrain surveying, battlefield surveying; tanks, aircraft, ships and artillery for distance measurement of targets; measuring clouds, aircraft, missiles and artificial satellites height etc. As the price of the laser range finder continues to drop, it is getting closer to our daily life.
House measurement has always been a work that the housing management department cares about and bothers, because the house survey and survey area map is the attached drawing on the resident's real estate certificate, which has legal effect, and it is directly related to the economic interests of ordinary people, so the accuracy of house measurement is very important. Particularly important. According to the previous methods, using a tape measure or a steel tape to measure, although it can be measured, there are large errors in the measurement of long distances, high floors, and difficult-to-reach places, and there are disadvantages such as high labor intensity and complicated work. Today, with the rapid development of high technology, this method obviously does not meet the requirements of rapid and high efficiency in today's information society. Fortunately, the laser rangefinder has appeared in this era. In the measurement of buildings with complex building structures, middle and high-rise buildings, and long distances, as long as they are aligned and scanned lightly, the results will come out. It is easy to use and the measurement data is accurate (1.5 mm accuracy ), work efficiency is improved, surveying and measuring errors are reduced, and the accuracy of area measurement is ensured. The result makes the owner more convinced.
In addition, the laser rangefinder plays a pivotal role in the traffic police case handling, which can effectively improve the efficiency and accuracy of traffic accident scene investigation. In the handling of traffic accidents, the measurement of the accident scene by the laser rangefinder is a very important link, which plays a key data support for the judgment of the vehicle speed at the time of the accident and the characterization of the accident. After the laser rangefinder has accurately measured the results, it can automatically input the on-site measurement data and related information into the portable computer through Bluetooth wireless communication, and use the computer's high-speed data calculation and graphics processing functions to quickly map out the standardized and accurate proportion of the traffic accident scene Maps and automatic generation of on-site investigation records have effectively improved the efficiency of traffic police handling cases.
In addition, laser range finders are also widely used in railway platforms, port terminals, cranes, etc. In recent years, under the premise of continuous advancement of science and technology, all walks of life have put forward higher requirements for the distance and accuracy of laser rangefinders, especially in the field of long-distance distance measurement. At the same time, it also focuses on the research of measurement accuracy and integration of multiple sensors, minimizes the error, and provides a variety of measurement functions to improve the overall performance of the laser rangefinder, thereby expanding the scope of practical applications.
In any case, the development prospect of the laser range finder is very clear. Relevant production enterprises should pay more attention to technical research and implement it to improve the overall performance of laser range finders, meet the different needs of various industries, and promote my country's instrumentation industry to a stage of high-quality development.
