SAFETY INSTRUCTIONS
HANDLE LASER DEVICE PROPERLY
HANDLE ELECTRICAL CONNECTION PROPERLY
CAUTION
This product emits an invisible laser beam with a laser safety rating of
Class 1.
CAUTION
Please do not open the LiDAR cover without authorization because the
laser might be still on after the cover is removed and the operator would be
exposed to laser.
CAUTION
It is not guaranteed that the laser remains Class 1 safety status after open-
ing the cover.
CAUTION
Disconnect the power supply when connecting or disconnecting electrical
cables.
CAUTION
The power supply connected with the device must comply with the require-
ments included in the operation instructions.
CAUTION
Please connect the reference potential properly when using the device to
avoid injury caused by equal potential current.

CHAPTER 3
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
