Explain the principle, application and advantages and disadvantages of laser level in detail！

Laser level is a tool used to measure the horizontal plane. It uses laser beam as the measurement reference line. It has the characteristics of high precision, high efficiency and high stability. It is widely used in construction, engineering, geology and other fields. This article will analyze the principle, application, advantages and disadvantages of the laser level in detail. 

First, working principle of laser level

The laser level uses the laser beam as the measurement reference line. It uses the linearity, monochromaticity, coherence and other characteristics of the laser beam to receive the laser signal through the photoelectric sensor and perform signal processing to finally obtain an accurate horizontal line. The main working principle of the laser level can be divided into three steps:

The first step, laser emission. The laser level generates a laser beam through a built-in laser transmitter, and the laser beam is emitted through a collimating lens or a prism to form a straight beam.

The second step is laser reception. The laser level receives the laser signal through the built-in photoelectric sensor, the sensor converts the laser signal into an electrical signal, and then processes it through the signal processor to finally get the position of the horizontal line.

The third step is to display the horizontal line. The laser level displays the position of the horizontal line through the built-in display screen or LED indicator to reflect the position of the horizontal plane.

Second, the application of laser level

1. Construction engineering field

Laser levels are widely used in the field of construction engineering, mainly used for level measurement of foundations, walls, ceilings, floors, etc. In terms of foundation measurement, the laser level can provide high-precision foundation elevation to ensure the levelness and flatness of the foundation; in terms of wall and ceiling measurement, the laser level can provide accurate horizontal lines to ensure the overall levelness and aesthetics of the building ; In terms of ground measurement, the laser level can quickly and accurately measure the slope and elevation of the ground, and is used for the construction of roads, bridges, tunnels and other buildings.

2. Industrial production field

The application of laser level in the field of industrial production is mainly reflected in the links of workpiece processing, assembly and calibration. It can provide a high-precision horizontal line for the positioning and calibration of the workpiece to ensure the accuracy and quality of the workpiece; at the same time, the laser level can also measure the levelness and flatness of the equipment for maintenance and maintenance of the equipment.

3. Geological exploration field

The application of laser level in the field of geological exploration is mainly reflected in topographic survey, geological exploration and so on. It can provide high-precision terrain elevation for geological exploration, terrain analysis, etc.; at the same time, the laser level can also measure the slope and elevation of the ground for the construction of roads, bridges, tunnels and other buildings.

4. Other fields

Laser levels are also widely used in aviation, aerospace, military and other fields. It provides high-precision horizon and inclination measurements for navigation and positioning.

Third, Advantages and disadvantages of laser level

advantage:

1. High precision: The laser level can provide extremely high measurement accuracy, reaching 0.1mm/m.
2. High efficiency: The laser level can quickly and accurately measure the level, improving work efficiency.
3. Easy to operate: the laser level adopts digital display, which is easy to operate and grasp.
4. Multi-function: The laser level can not only measure the horizontal line, but also can measure the inclination angle, vertical line, etc., with multiple functions.

shortcoming:

1. High environmental requirements: The laser level needs to be used in a relatively stable environment to avoid interference from factors such as temperature and humidity, otherwise the measurement accuracy will be affected.
2. The lines are limited: the measurement range of the laser level is limited by the laser beam, and it cannot measure non-linear lines.
3. Short battery life: The laser level is powered by batteries, the battery life is relatively short, and the batteries need to be replaced frequently.
