When buying a laser rangefinder, three issues and solutions need to be taken into account.
There are three points that must be considered when purchasing a laser rangefinder: measurement range, measurement accuracy, and use occasions.
1. Only need to measure the distance within a few meters or more than ten meters, and the accuracy requirement is not high.
It is recommended to use "Ultrasonic Range Finder". The measurement effect of the ultrasonic range finder is greatly affected by the environment, and its stability and directionality are worse than that of the laser range finder, but the price is relatively cheap, and it is suitable for indoor measurement.
2. The measurement distance is not long, and it is mostly used indoors with high precision requirements.
It is recommended to purchase "Handheld Laser Rangefinder". The handheld laser rangefinder is suitable for indoor use, and the measurement accuracy and effect are very good. If the user needs to detect in an outdoor environment, it is recommended to use a professional laser sight and a reflector to achieve the expected range and effect.
3. The measurement distance is relatively long, and it is mostly used for outdoor use.
It is recommended to purchase a "telescopic laser rangefinder", namely: a laser rangefinder telescope.
The laser rangefinder is an instrument that uses laser to accurately measure the distance of the target.
When the laser range finder is working, it emits a very thin laser beam to the target, and the photoelectric element 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.
If the laser is emitted continuously, the measurement range can reach about 40 kilometers, and the operation can be carried out day and night.
If the laser is emitted in pulses, the precision is generally low, but it can achieve good relative precision when used for long-distance measurement.
The laser range finder 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;
Therefore, it is widely used in terrain measurement, battlefield measurement, distance measurement of tanks, aircraft, ships and artillery to targets, and measurement of altitude of clouds, aircraft, missiles and artificial satellites.
It is an important technical equipment to improve the accuracy of high tanks, aircraft, ships and artillery.
Due to the continuous reduction in the price of laser range finders, the industry has gradually begun to use laser range finders.
At home and abroad, a batch of new miniature rangefinders with the advantages of fast ranging, small size and reliable performance have emerged, which can be widely used in industrial measurement and control, mines, ports and other fields.
