MULTI-OBJECT, WIDE-BEAM OPTICAL DETECTION
AND RANGING OVER EIGHT SEGMENTS.
THE SMALL, AFFORDABLE,
VERSATILE LiDAR
LeddarVu solid-state LiDAR sensors offer affordable
detection and ranging performance in a small, robust form
factor over distances up to 185 m.
Leveraging LeddarTech’s unique expertise in LiDAR
detection and ranging, every LeddarVu sensor contains
our proprietary Leddar technology. The patented Leddar
signal processing algorithms efciently acquire, sequence
and digitally process light signals, signicantly improving
solid-state LiDAR sensitivity, immunity to ambient light and
performance in inclement weather.
This unique built-in processing ability allows for rapid
delivery of accurate measurements, and extends range and
measurement capabilities. Additionally, it provides superior
lateral discrimination, as well as the critical capability to
detect and track multiple objects simultaneously in the
sensor’s eld of view (FOV).
VU8 CONFIGURATIONS
Weighing only 128.5 grams or less, LeddarVu Vu8 modules
use a xed light source, which signicantly increases the
sensor’s robustness and cost-efciency as compared to
any scanning LiDAR solution.
The Vu8 leverages powerful laser illumination (class 1,
eye-safe) and a wide FOV separated into eight distinct
detection segments within a single sensor, resulting in
rapid, continuous and accurate detection and ranging of
objects—including lateral discrimination—along the entire
length of the wide beam, without any moving parts.
The Vu8 source assembly consists of a 905 nm laser
emitter combined with diffractive optics, providing a wide
illumination beam that is available in various horizontal
FOV congurations from 20 to 100 degrees (each available
in different vertical FOVs). The receiver assembly includes
eight independent detection elements with simultaneous
multi-object measurement capabilities supported by
powerful Leddar signal processing algorithms.
INTEGRATION AND INTERFACES
All Vu8 modules come with a software development kit,
the Leddar Enabler SDK, which provides a user-friendly
application programming interface (API) with .NET and C
libraries complete with code examples and sample code
for Windows and Linux. Two interface congurations are
available: SPI or USB-CAN-Serial (UART/RS-485).
