General concept
An instrument that projects a visible laser beam according to which the height can be leveled. Another concept is to make the visible laser point (generally red light and green light) sweep the light of the same Leveling Height under the drive of the fast rotating axis, which is a kind of instrument for engineers to locate the leveling height.
working principle
For the planimeter which projects the visible beam, it is to use the visible beam to fix the height (the light propagates in a straight line).
For the instrument of light spot scanning line, it uses the principle that when the visible laser spot is moving rapidly, because the human vision is temporary, people see that the movement of light spot is a line. When the instrument is leveled, the photoelectrically swept lines are at the same height.
Folding type
At present, according to the working principle and whether to add a compensation mechanism or not, the laser scanners commonly used in China can be roughly divided into three categories: bubble laser scanners, automatic leveling laser scanners and electronic automatic leveling laser scanners.
