What is the Pulsar ME450 and what is it used for?

The Pulsar ME450 is a cost-effective dToF (direct Time-of-Flight) 3D LiDAR with configurable scanning patterns. It pairs a MEMS-based pitch scanner with motorized azimuth control and emits 200kHz laser pulses, scanning across a 270 degree horizontal and 60 degree vertical field of view. It is used for robot positioning and navigation, obstacle perception and avoidance, area security, logistics, environmental scanning, and 3D reconstruction.

What scanning patterns does the Pulsar ME450 support?

The Pulsar ME450 supports multiple configurable patterns: non-repetitive scanning and repetitive scanning at non-dense, 2x dense, and 4x dense settings. Vertical field of view and rotational speed are also adjustable, so a single device covers different 3D data acquisition needs without swapping hardware.

What is the detection range of the Pulsar ME450?

The Pulsar ME450 has a maximum measurement range of 45m at 90% reflectivity and 15m at 10% reflectivity, using a 905nm (plus or minus 10nm) laser rated Class 1 for eye safety.

What is the accuracy and precision of the Pulsar ME450?

The Pulsar ME450 is rated for accuracy of plus or minus 30mm and precision of 20mm or better. It can reach millimeter-level accuracy under typical indoor conditions, for example white walls within 30m or 10% reflectivity targets within 10m; in outdoor or long-range cases the error may exceed 10mm.

What is the field of view and scanning frequency of the Pulsar ME450?

The Pulsar ME450 covers a 270 degree horizontal field of view and a 60 degree vertical field of view. It operates at a 200kHz measurement frequency with a 20Hz horizontal rotation frequency, and includes a built-in 6-axis IMU.

How does the Pulsar ME450 handle interference and harsh environments?

The Pulsar ME450 is engineered to withstand vibration and shock, carries an IP67 dust and waterproof rating, and tolerates ambient light above 80,000 lux. It also provides crosstalk immunity in multi-device opposed-beam systems, allowing multiple units to operate facing each other without interference.

What is the operating temperature range of the Pulsar ME450?

The Pulsar ME450 operates in ambient temperatures from -20 degrees C to 55 degrees C, with a storage range of -40 degrees C to 70 degrees C. It measures 65mm x 83mm x 65mm and weighs about 270g.

What applications is the Pulsar ME450 best suited for?

The Pulsar ME450 is well suited to robotic lawn mowers, forklifts, warehouse AMRs, and logistics vehicles, along with general-purpose laser scanning for surveying and 3D reconstruction. It is supported across the full Orbbec SDK suite, and Orbbec Viewer provides LiDAR-focused preview and configuration.
