The simple power supply schema saves LIDAR system’s BOM cost and makes

RPLIDAR A1 much easier to use. Detailed specification about power and

communication interface can be found in the following sections.

Mechanism

RPLIDAR is based on laser triangulation ranging principle and uses high-speed

vision acquisition and processing hardware developed by SLAMTEC. The system

measures distance data in up to 8000 times’ per second and with high resolution

distance output (<1% of the distance).

RPLIDAR emits modulated infrared laser signal and the laser signal is then

reflected by the object to be detected. The returning signal is sampled by vision

acquisition system in RPLIDAR A1 and the DSP embedded in RPLIDAR A1 start

processing the sample data and output distance value and angle value between

object and RPLIDAR A1 through communication interface.

Figure 1-2 The RPLIDAR A1 Working Schematic

The high-speed ranging scanner system is mounted on a spinning rotator with a

build-in angular encoding system. During rotating, a 360 degree scan of the

current environment will be performed.
