What is the working principle of automatic correction of Tiling Floor 3D Green Laser Level?

Using the monochromaticity and coherence of the laser, a glass or metal plate with a certain shading pattern, namely a zone plate, can be assembled in front of the telescope objective to generate diffraction interference. Through telescope focusing, a bright and fine cross or circular laser spot is obtained within the focusing range of the zone plate, so as to more accurately aim at the target.

If the front and rear leveling rulers are equipped with photoelectric receiving targets that can be automatically tracked, leveling can be carried out. In construction survey and large component assembly,Tiling Floor 3D Green Laser Level is often used to establish horizontal plane or horizontal line. Through the digital imaging system built in the instrument, the bar code reading of the level bar is automatically obtained, and manual reading is no longer required. The laser level can greatly reduce the labor intensity of surveying and mapping, avoid artificial subjective reading error, and improve the measurement accuracy and efficiency.
