found in the following sections.

Mechanism

The RPLIDAR A3M1 is based on laser triangulation ranging principle and adopts

the high-speed vision acquisition and processing hardware developed by

SLAMTEC. The system ranges more than 16000 times per second.

Figure 1-2 The RPLIDAR Working Schematic

During every ranging process, the RPLIDAR emits modulated infrared laser signal

and the laser signal is then reflected by the object to be detected. The returning

signal is then sampled by vision acquisition system in RPLIDAR and the DSP

embedded in RPLIDAR starts processing the sample data and outputs distance

value and angle value between object and RPLIDAR via communication interface.

When drove by the motor system, the range scanner core will rotate clockwise

and perform the 360-degree scan for the current environment.
