Detect, Locate, Measure with Leddar Solid-State LiDAR Sensing

The possibilities of the Leddar technology

Leddar™ is a unique detection and ranging technology used to resolve the distance between a sensor and remote objects, effectively detecting and locating them. Its proprietary and patented design provides unique benefits compared to other similar technologies such as radar and sonar. Leddar drastically expands the possibilities of solid-state LiDAR sensors and is used in several markets such as automotive, drones, industrial vehicles, traffic / transportation as well as level sensing, to only name a few.

picto presence detection

presence detection

Leddar can be used for object detection in the field of view of the sensor. Applications commonly referred to as motion detection, occupancy sensing or proximity sensing can all be implemented with Leddar. The range and field of view of the sensor are determined by the optical design and Leddartech offers several configurations ready for use. Additionally, optics can be tailored to a specific application to match the field of view to the required detection zone. Leddar is particularly adapted to long range and large area detection applications.

picto collision avoidance 500

collision avoidance and navigation

When used with wide field of view optics configurations, Leddar’s multiple segment solutions (8 or 16) can be used to provide any vehicle with obstacle detection capabilities (pedestrian, vehicle and general object) or autonomous navigation assistance.

distance measurement

The unique capabilities of Leddar provide reliable and accurate distance measurement of detected objects in the field of view. Leddartech’s multiple-segment solutions also provide an angular position of the objects and return multiple object detection and ranging measurements. Furthermore, Leddar proprietary processing algorithms provide discrimination of two or more objects in each segment of the field of view. Finally, an amplitude indicating the strength of the object detection signal (quantity of reflected light from the object) is reported.

picto speed 500

tracking and speed measurement

Leddartech’s multiple segment solutions (8 or 16) at high measurement rates can be used to identify objects, measure speed, track their position and trajectory. This can be applied to a wide range of applications including automotive driver assistance systems, autonomous vehicle obstacle detection and navigation, traffic monitoring and road speed enforcement systems.

object profiling and classification

Leddar’s multiple segment solutions (8 or 16) can be used to profile objects when they occupy several segments. This provides the capability to estimate the size and shape of the objects and classify them or validate these characteristics against application-defined criteria. For example, in an automated tolling application, the vehicle type can be determined for verification that user is paying the right fee.

picto gesture 500

gesture recognition

Leddar can be used to detect simple hand gestures, with a superior detection range compared to similar technologies. Left or right swiping and tapping at precise lateral positions can be used at short range while maintaining presence detection capabilities of people up to several meters away from the sensor.
