Polar Coordinate System
The Lidar Mini uses a polar coordinate system. The center of the rotating core serves as the pole. The arrow marks the zero direction, and clockwise rotation defines the positive direction.
Laser Emission Center
The lidar laser emission center sits 31.3 mm above the bottom of the mounting clip.
