The RPLidar A2 has a scan rate of up to 15Hz, providing 4000 samples/second. The plane is determined by the orientation of the sensor. This is a ‘2D’ lidar in that it can measure multiple points on a given plane. Then it does some maths, and calculates the distance to the object. Because the receiver knows when the light was emitted, it can measure accurately how long it takes for the light to reflect back from any objects in the lights path. The laser emits light, the receiver receives the light. The RPLidars work by rotating a laser emitter and receiver. Both the A2 and the A3 have the same footprint, and use the same mounting pattern for attachment. ![]() The prices range from ~$320 USD for the A2 to $600 for the A3. Slamtec sells a couple of different versions of the A2, and also sells a more capable A3 version. The RPLidar A2 is a popular low cost 2D LIDAR. ![]()
