WORKING PRINCIPLES
LGS-N50 is a 2D LiDAR sensor developed to meet the needs of Object Localization. The
output of this product is point cloud data (Ethernet port).
A laser beam emitted from LGS-N50 internal laser diode is projected around LiDAR
through a rotating mirror and then returns (the amount of returned laser energy
depends on the reflectivity of objects). The LiDAR obtains the detected distance and
angle information through calculation, as shown below.
Figure 1 - LGS-N50 LiDAR working principle
Based on the TOF (Time of Flight) principle, the distance between objects and LiDAR is
obtained according to the speed of light and time of flight of the laser. The calculation
method is as follows:
D=c*T/2
Where:
D = distance
T = flying time
c = speed of light
