What are the development prospects of laser distance meters in my country?
As a factory in the world, the laser distance meter industry has good prospects and potential. Since the 21st century, China's laser market has shown a steady and rapid growth trend. Although the industry is developing rapidly, we should be aware that China's laser industry started late and has a weak foundation, and there is still a big gap with major countries in the world. For example, compared with laser processing systems manufactured in advanced countries, Chinas laser processing systems are quite different. It only accounts for about 2% of global sales. Mainly reflected in: the high-end laser processing system is few and uneven; the laser of the main part of the laser distance meter is not turned off; there is a big gap in the laser micro-processing equipment.
There are still many main problems
Few core technologies: Many key basic technologies have not been resolved, and some technologies have even regressed. At present, most of the core technologies of domestic laser distance meters are imported, and the competitiveness of the products is insufficient.
The combination of product research and development is not satisfactory: China is still a world leader in the academic research of laser distance meters, but the industry is very backward, intellectual property rights and patent results are not well protected, and many advanced laser technologies have not been transformed into industry application. In addition, academic openness is not enough, and innovation efficiency is low due to concerns about technology loss.
Weak innovation ability and poor support ability: The system support ability is not high, and the innovation ability is insufficient. Most of them are traditional structure types. At present, most industries are integrated industries of optomechanics and electronic computing. The combination of domestic lasers and other industries is very poor, and the degree of intelligence and automation is low, which increases the difficulty for users.
From the perspective of technology management, there is a lack of a good evaluation system: lack of national standards, the evaluation system is "equivalent" improperly converted, and it is not flashy. The existing evaluation system is a self-circulation, leading to insufficient quality supervision of laser products, which is not conducive to the development of the laser industry.
Laser's Monochromaticity And Strong Directionality
Laser distance measuring uses a laser as a light source for distance measurement. According to the laser working mode, it is divided into continuous laser and pulsed laser. Gas lasers such as helium-neon, argon ion, krypton-cadmium, etc. work in a continuous output state for phase laser ranging; double heterogeneous gallium arsenide semiconductor lasers for infrared ranging; solid lasers such as ruby and neodymium glass are used for Pulse laser ranging.
Compared with the photoelectric rangefinder, the laser rangefinder can not only work day and night, but also improve the accuracy of range measurement and significantly reduce the weight due to the characteristics of the laser's monochromaticity and strong directionality, coupled with the semiconductor integration of the electronic circuit. And power consumption, so that the measurement of the distance to the artificial earth satellite, the moon and other distant targets becomes a reality.
If you were to use a laser distance meter instead of a soft ruler or tape measure to measure distance, what would you use it to measure?
Facilities: layout
1. Bid calculation (HVAC, electricity, cables, maintenance), measuring distance, area and/or volume.
2. Measure the height or width of buildings and other objects. Triangulation can be used when necessary.
3. CAD The calculation of the built buildings and design drawings.
4. Determine whether the sides of the room or object are truly vertical or completely parallel.
5. Parking lot layout.
6. Check whether the new building meets the requirements for use.
7. The occupancy size of the equipment or office cubicle to help layout the office layout.
8. Determine the size of the built building without drawings.
9. Calculate the internal area/volume of a room or building.
