Two-Dimensional Laser Lidar

LES-25D-C30R/LES-40D-C30R/LES-25D-C30E/LES-40D-C30E is a cost-effective two-dimensional pulse lidar developed by Pacecat. It uses a pulsed laser to emit a single laser pulse to the target, and calculates and processes the round-trip time by receiving the laser pulse echo which is diffusely reflected from the target.The distance data and Angle information of the computing target are sent to other devices through the serial port.It has a high speed laser ranging sampling capability of up to 18,000/36,000 times per second.Combined with the optical magnetic fusion technology, it overcomes the life limit of traditional lidar, and run reliably and stably for a long time.

Product Features

  • Lidar has the functions of hardware filtering and dragging point removal, which can effectively avoid some interference caused by noise points.
  • Lidar can synchronously output the target reflection intensity, which can be used for algorithm judgment;
  • The ranging accuracy is ±3cm, and the linear characteristics of different targets are excellent.
  • Multi-lidar operation at the same time, no interference between lidars;
  • Special optical design, effectively improve the anti-fouling ability;
