LS Lidar Terminator 1 500m 1550nm Automotive 3D LiDAR

Long Range 1550 nm LiDAR for Advanced 3D Perception

The LS Lidar Terminator 1 is an image-grade hybrid solid-state LiDAR designed for autonomous vehicles, ADAS development and other perception systems that need to identify objects at long range. Using a 1550 nm fiber laser, the sensor combines extended detection distance with dense point-cloud output and configurable scanning patterns to provide detailed information about vehicles, pedestrians, road infrastructure and smaller objects ahead of the platform.

Its combination of 250 m detection at 10% reflectivity, up to 500 m maximum range and a wide 120° × 25° field of view makes Terminator 1 particularly suitable for forward-facing perception where early object detection is important.

250 Metres at 10 Percent Reflectivity

Terminator 1 is specified for approximately 250 metres at 10% target reflectivity, with maximum detection extending to approximately 500 metres under suitable conditions. The 10% reflectivity figure is particularly relevant for automotive and machine-perception applications because dark vehicles, tyres, clothing and road materials reflect less laser energy than brighter objects.

For autonomous driving and high-speed vehicle applications, long-range detection gives the perception system more distance over which to identify an object and determine its position. Actual range will still depend on target reflectivity, weather, installation angle and environmental conditions.

1550 nm Fiber Laser Technology

The Terminator 1 uses a 1550 nm Class 1 fiber laser. LS Lidar developed this architecture to support long-range measurement, fine beam control and strong resistance to optical interference while maintaining the required eye-safety classification under specified operating conditions.

The 1550 nm wavelength is particularly useful for long-range automotive LiDAR because it allows the sensor to work with higher optical power than many conventional near-infrared systems while remaining within Class 1 safety limits when properly engineered.

High Density Point Cloud Output

Depending on the selected configuration, Terminator 1 generates approximately 1.65 to 1.85 million measurement points per second. This dense point cloud allows perception software to represent object contours and road geometry in considerably more detail than a simple distance sensor or low-channel LiDAR.

For real-world autonomous driving, the additional measurement density helps the system detect smaller targets and maintain a clearer representation of distant vehicles, pedestrians, roadside structures and other features.

120 Degree by 25 Degree Field of View

The sensor provides a 120° horizontal field of view combined with approximately 25° vertical coverage. This creates a broad forward-facing measurement area suitable for mounting in the front or roofline of a vehicle.

The wide horizontal angle provides good coverage across several lanes and surrounding road edges, while the vertical field of view captures objects at different heights and road gradients. This makes the sensor suitable for both highway and urban perception systems.

Configurable Region of Interest Scanning

A major feature of Terminator 1 is its support for different Region of Interest scanning patterns. LS Lidar describes uniform scanning, fixed ROI scanning and non-uniform or dynamic ROI options depending on the configuration.

ROI scanning allows additional measurement density to be concentrated in the parts of the field of view that matter most. For example, a perception system can place higher resolution around the road ahead or another long-distance target area rather than distributing all points evenly across the entire scene.

Better Small Object Detection at Distance

Fine angular resolution and dense ROI scanning help Terminator 1 place more laser measurements on relatively small distant objects. This is valuable for detecting pedestrians, road debris and other targets that may occupy only a small portion of the sensor’s field of view at long range.

LS Lidar specifically highlights pedestrian and dark-vehicle detection at approximately 250 m as a key use case. For autonomous-driving developers, the practical benefit is a longer observation distance for objects that can be difficult to detect with lower-resolution LiDAR systems.

±2 cm Range Accuracy

The current Terminator 1 specification gives a range accuracy of ±2 cm. This provides consistent distance measurements for locating objects within the 3D point cloud and supporting object tracking, localisation and perception algorithms.

Final system performance will also depend on sensor calibration, vehicle movement, software processing and any camera, radar, GNSS or IMU data fused with the LiDAR measurements.

10 Hz Real Time Environmental Updates

The sensor operates at a 10 Hz frame rate, refreshing the complete point-cloud scene ten times per second. This is designed for real-time vehicle perception rather than static surveying.

At vehicle speeds, a consistent 10 Hz LiDAR feed provides perception software with regularly updated information about moving vehicles, pedestrians and changes in the road environment while keeping the point density high.

Ultra Thin Vehicle Integration

Terminator 1 uses an ultra-thin housing measuring approximately 231 × 132 × 46 mm according to the current manufacturer page. This low-profile design makes it easier to integrate the LiDAR into vehicle bodywork, roof modules or dedicated perception housings without requiring a tall rotating sensor.

The hybrid solid-state architecture is intended for integrated vehicle installations where dimensions, aerodynamics and appearance are important alongside measurement performance.

Automotive and Industrial Ethernet

The LS-S3 platform supports Automotive Ethernet and Industrial Ethernet configurations. This allows the high-rate point-cloud stream to be transferred to an autonomous-driving computer, perception controller or other embedded processing platform.

The exact network interface and temperature specification depend on the supplied configuration, so engineers should match the selected Terminator 1 variant to the vehicle network and processing architecture before integration.

Low Power for a Long Range LiDAR

The LS-S3 platform is specified with power consumption of 25 W or less and an input voltage range of approximately 9–36 VDC. This provides flexibility when integrating the sensor into vehicle electrical systems and other mobile platforms.

Keeping power consumption relatively low is important because modern autonomous vehicles may operate several LiDAR sensors, cameras, radars and high-performance computers at the same time.

Designed for Demanding Vehicle Environments

Terminator 1 carries an IP6K9K environmental protection rating. The LS-S3 technical sheet also specifies resistance to vibration and mechanical shock for use in vehicle applications.

Operating temperature depends on interface configuration. The technical sheet lists approximately -40°C to +85°C for Automotive Ethernet versions and approximately -20°C to +65°C for Industrial Ethernet versions. This distinction is important when selecting a variant for automotive or industrial development.

LiDAR for Sensor Fusion

Terminator 1 is designed to work as part of a complete perception system rather than as a standalone navigation device. Its 3D measurements can be combined with cameras, radar, GNSS and IMU sensors to create a more complete understanding of the vehicle environment.

LiDAR provides accurate 3D distance and geometry, cameras provide colour and visual information, radar performs well for object speed and certain weather conditions, while GNSS and IMU sensors provide vehicle position and movement. Combining these data sources allows perception software to use the strengths of each technology.

Choosing the Correct Terminator 1 Configuration

The Terminator 1 platform is available in several LS-S3 configurations with different channel counts, angular resolutions and ROI patterns. The exact choice depends on the required point density, target region and vehicle integration requirements.

For applications that need more detail in a specific long-range area, an ROI-focused configuration can provide higher measurement density where it is most useful. Projects requiring more uniform environmental coverage may be better suited to a configuration that distributes points more evenly across the field of view.
