The principle of telescopic rangefinder and its key points of selection
Telescopic rangefinders usually use the pulse method to measure distance.The pulse method works as follows: the laser emitted by the rangefinder is reflected off the object to be measured, and is then received by the rangefinder, which simultaneously records the time of the laser round trip.Half the speed of light times the round trip time is the distance between the rangefinder and the object being measured.The accuracy of the pulse method used to measure the distance is usually about +/- 1 m.In addition, such rangefinders typically measure dead zones of about 15 meters.
Points of selection
1. The basic parameter of a telescopic rangefinder is to measure distance.First, you should choose a telescopic rangefinder that needs to measure distance.
2. Measurement accuracy. The nominal measurement accuracy of all manufacturers is +/- 1 meter, which is only theoretical data.The measurement accuracy depends on the target environment, telescope rangefinder lens, infrared laser emitter quality and data processor accuracy.
What is the development prospect of laser rangefinder in China?
As the world's factory, laser rangefinder industry has a good prospect and potential. Since the 21st century, China's laser market has shown a steady and rapid growth trend.Despite the rapid development of the industry, we should be aware that China's laser industry started late, the foundation is weak, and the gap with the world's major countries is still large. For example, China's laser processing systems are quite different from those made in advanced countries.It accounts for only about 2% of global sales.Mainly reflected in: high-end laser processing system less, uneven;The laser of the main component of the laser rangefinder is not closed;There is a big gap in laser micromachining equipment.
Major problems remain:
There are fewer core technologies: many of the key infrastructure technologies have not been solved, and some technologies have even regressed.At present, most of the core technologies of domestic laser rangefinder are imported, and the competitiveness of the products is insufficient.
The combination of product research and development is not satisfactory: China still leads the world in academic research on laser rangefinders, but the industry is very backward, intellectual property rights and patent results are not well protected, and many advanced laser technologies have not been translated into industrial applications.In addition, academic openness is not enough, and innovation is inefficient due to the fear of technological loss.
Weak innovation ability, poor support ability: the system support ability is not high, the innovation ability is insufficient, mostly is the traditional structure type.At present, most industries are integrated industries of optical machinery and electronic computing, and the combination of domestic laser and other industries is very bad, low degree of intelligence and automation, which increases the difficulty of users.
From a technical management perspective, there is a lack of a good evaluation system: there are no national standards, the evaluation system "equivalence" conversion is improper, not flashy.The existing evaluation system is a kind of self-cycle, which leads to the insufficient quality supervision of laser products and is not conducive to the development of laser industry.
