Pulsar SL450
Cost-effective Single-line LiDAR for Robotic Navigation
dToF l High-accuracy l Long-range l IP65
Introduction
Pulsar SL450 employs direct Time of Flight (dToF) ranging technology. It’s constructed around a high-precision rotating-mirror optical scanning system and a high-frequency laser pulse transmitter. Sophisticated optical, mechanical, and structural design permits robust and accurate scanning within a 270° horizontal area, up to a distance of 45m. SL450 can be used in many fields, including robot positioning and navigation, area security, logistics, environmental scanning, and 3D scene reconstruction.
High-density Point Cloud Scanning
With a scanning frequency of up to 72 kHz and an angular resolution as fine as 0.075°, it ensures highly detailed surface scanning without missing any details.
Robust Environmental Perception
Reliable ranging capability, combined with a multi-echo noise filtering design, enables precise scanning and accurate data feedback, even in environments containing light dust or fog.
Accurate and Consistent Mapping
High degree of point cloud consistency, ensuring uniform distribution of accuracy and precision trends, and avoiding the presence of varying positive or negative offsets. This enables each sensor to generate maps of consistent quality, enabling reliable environmental reconstruction.
