Application Analysis of Laser Rangefinder

With the rapid development of laser technology, laser ranging has become a typical application of laser technology. In some non-contact, high-precision measurement occasions, laser ranging technology shows a strong advantage. Today's laser ranging sensors use a simple statistical principle, that is, the average rule achieves a resolution of 1mm and can guarantee a response speed.

The long-range laser rangefinder emits a very thin laser beam to the target during operation. The photoelectric beam receives the laser beam reflected by the target. The timer measures the time from the launch to the reception of the laser beam, and calculates the distance from the observer to the target. ; The LED white light velocimeter is imaged on the integrated circuit chip CCD in the instrument. The CCD chip has stable performance, long working life, and is basically not affected by the working environment and temperature. Therefore, the measurement accuracy of the LED white light velocimeter is guaranteed, and the performance is stable and reliable.

Laser rangefinders now play a certain role in all walks of life. They are widely used in terrain measurement and battlefield measurement; ranging of targets by tanks, aircraft, ships and artillery; measurement of clouds, aircraft, missiles and satellites Height and so on. As the price of laser rangefinders continues to fall, it is getting closer to our daily lives.

Housing measurement has always been a concerned and troublesome task for the housing management department, because the area chart of the housing survey is a drawing on the resident's real estate certificate and has legal effect. It is directly related to the economic interests of the people. Therefore, the accuracy of housing measurement appears Particularly important. Although it can be measured using a tape measure or a steel tape measure according to the previous methods, there are large errors in long-distance measurement, measurement of the height of the layer, and difficult-to-reach places, and the disadvantages of high labor intensity and complicated work. With the rapid development of high and new technology today, this method has obviously not met the requirements of the rapid and high efficiency of today's information society. Fortunately, laser rangefinders have appeared in this era. In the measurement of houses with complex building structures, high-rises, and long-distances, as long as they are aligned and scanned gently, the results come out. The use is simple and the measurement data is accurate (1.5 mm accuracy ), Improve work efficiency, reduce survey and survey errors, ensure the accuracy of area measurement, and as a result, the owner is more convinced.

In addition, laser rangefinders play a pivotal role in handling traffic police cases, which can effectively improve the efficiency and accuracy of traffic accident scene investigation. In the handling of traffic accidents, the laser rangefinder is an important part of the accident scene measurement, which plays a key role in determining the speed at the time of the accident and the characterization of the accident. After the laser rangefinder accurately measures the results, it can automatically input the field measurement data and related information into the portable computer through Bluetooth wireless communication. Using the computer's high-speed data calculation and graphic processing functions, it can quickly and accurately map the standardized and accurate traffic accident scene ratio. The map and automatically generated on-site investigation transcripts have effectively improved the efficiency of traffic police handling cases.

In addition, laser rangefinders are also widely used in railway stations, ports and cranes. In recent years, with the continuous advancement of science and technology, various industries have put forward higher requirements for the range and accuracy of laser rangefinders. Especially in remote ranging, many companies focus on this direction and improve distances. At the same time, we also focus on the measurement accuracy and the integration of multiple sensors to reduce errors as much as possible, and provide multiple measurement functions to improve the comprehensive performance of the laser rangefinder, thereby expanding the practical application range.
