Scalable Platform Points Way Toward High-Resolution LiDAR

13 September 2016

LeddarTech, a developer of solid-state light detection and ranging (LiDAR) technology, has introduced a new platform for the next generation of the company's LiDAR modules. According to LeddarTech, the platform—launched under the brand name LeddarVu— combines the benefits of a very compact, modular architecture with superior performance, robustness and cost efficiency toward high-resolution LiDAR applications, such as autonomous driving.

LeddarTech says its LeddarVu sensors will evolve along with future generations of the LeddarCore ICs. According to the company's previously announced development roadmap, upcoming iterations of LeddarCore ICs are expected to deliver detection ranges reaching 250 m, fields of view up to 140° and data capture rates up to 480,000 points per second (with a resolution down to 0.25° both horizontal and vertical), enabling the design of affordable LiDAR sensors for all levels of autonomous driving, including the capability of mapping the environment over 360° around the vehicle.

LeddarVu also adds the capacity to interchange various types of optical components from different suppliers to ensure the rapid development and integration of new module configurations that are optimized for specific applications or requirements.

Vu8—An eight-segment LiDAR sensor module

LeddarTech showcased the Vu8, the first module based on the new LeddarVu platform. The Vu8 is a compact, solid-state LiDAR module that provides accurate multi-target detection over eight independent segments. Detecting targets at up to a 215 m range and weighing only 75 grams, the Vu8 delivers nearly twice the range for half the volume compared with LeddarTech's existing M16 module. The Vu8 uses a fixed laser light source, which significantly increases the sensor's robustness and cost efficiency compared with any scanning LiDAR solution.

LeddarVu's high tolerance to noise and interference means it remains unaffected by other sensors' signals and by lighting conditions including direct sunlight, and it provides reliable detection in various weather conditions, including rain and snow.

The company positions the new Vu8 sensor as particularly suited for navigation and collision avoidance applications in driver-assisted, semi-autonomous and autonomous vehicles, such as drones, trucks, heavy equipment for construction and mining, shuttles, buses and other public transportation vehicles. Applications such as advanced traffic management systems requiring longer ranges as well as wide fields of view will also benefit greatly from the new Vu8 sensor offering.

The Vu8 modules are available today in various field-of-view options at a list price starting at $475, with discount quantities available.
