High Speed Multi-Return Lidar Systems
Up to 150 meters at 800K pulses per second
Up to 300 meters at 200K pulses per second
Up to 4 returns per pulse
Six axis IMU included (AL-500)
PPS and NMEA inputs for dynamic GPS sync

The AL-500 scene scan lidar and AL-500AIR line scan lidar systems offer programmable scan rates of up to 800,000 laser pulses per second and 300 scan lines per second, covering 120 degrees per line. Both can transmit up to 6667 pulses per line and capture up to 4 returns per pulse. Scan rates, fields of view, and laser pulse rate are controlled from the notebook based interface or through Acuity's Lidar Application Programming Interface routines available for Linux and Windows. Control and data communications use a 100 Mb ethernet link.

For mobile systems, PPS and NMEA inputs are used to synchronize the scanners with external GPS receiver time signals, allowing point-by-point transformation of scanner output to an inertial or ECEF frame of reference.

AL-500 two-axis Lidar and AL-500AIR line scan Lidar

AL-500

The AL-500 is a two-axis lidar system for autonomous vehicles, industrial use, and general 3D scene capture. By combining a fast vertical scan rate with precision turret rotation the AL-500 can acquire range imagery across a wide range of scan speeds and resolutions. The AL-500 has unlimited continuous turret rotation at up to 10 revolutions per second. The turret can reverse direction for repeated narrow field of view scanning.

Applications
  • Vehicle navigation and obstacle detection
  • Crime scene reconstruction
  • Accident scene reconstruction
  • As-built plant capture
  • Forest inventory
AL-500AIR

The AL-500AIR is a lightweight line scan lidar designed for airborne mapping and continuous or batch industrial point cloud acquisition. Weighing only 1.3 Kg and consuming 6 to 50 watts the AL-500 is well suited for small drones at altitudes up to 200 meters AGL.

Applications
  • Drone and air vehicle airborne mapping
  • Process monitoring and recording
API for Linux and Win10

Source code for controlling the AL-500 and AL-500AIR and collecting scans is supported under Windows 10 and Linux. A standalone demonstration application for connecting to a scanner, configuring scan parameters, obtaining scan data, and storing it to disk is included. API documentation is found in the AL-500 and AL-500AIR Users Manuals.

Acuity PointWorks

Acuity's PointWorks software is included with the AL-500 and AL-500AIR, with C++ source for control and data collection programming. Pointworks also provides interactive point cloud visualization and data export in standard file formats. For advanced processing, PointWorks' .LAS output can be used with any of several available point cloud manipulation and analysis packages.

Configuration Options

The AL-500 and AL-500AIR may be configured for a wide range of sample rates, scan speeds, laser power, and maximum number of returns. Most settings are user-programmable, while some require factory configuration.
