Figure 3. Sample trace, where the x-axis is a time axis, scaled into distance, and the y-axis is the light amplitude.
Figure 3 illustrates a typical trace signal for one segment. In this example, the sensor is collecting
light reflected back by two separate objects. Full waveform analysis performed by Leddar
sensors provides the capacity to detect multiple objects in the same segment. This is possible if
the closer object is smaller than the illuminated area for that segment. The beam can then
illuminate another object that isn’t completely “shadowed” by the closer object.
Benefits of Leddar Technology
When compared to other detection technologies such as laser scanners, radar, video, thermal
imaging, ultrasonic and passive infrared, Leddar excels on the widest range of performance
criteria, due to its ruggedness, rapid data acquisition, 16 independent segments (multi-element
platform) and simultaneous acquisition capabilities. Optimized for detection and ranging up to
100 m or more, Leddar can efficiently and cost-effectively serve multiple industries.
In addition, this technology is available in various module forms, with or without enclosure. As
an opto-electronic technology, it can easily be adapted to almost any final application.
Of particular benefit to developers and integrators is the technology’s unmatched
cost/performance ratio, its ability to detect multiple objects in each segment and lateral
discrimination (multi-element platform), its long detection range with low-power LEDs, real-
time object-tracking capabilities, detection in adverse weather conditions, and ocular safety.
