For an in-depth look into Leddar technology, nothing does it like our latest white paper, fresh from our engineers.

This technical work covers the core concepts of Leddar, describes its main advantages compared to other methods and provides an overview of the architectural components of a Leddar-based sensor. Here’s an excerpt:

 

“… The first benefit of Leddar optical time-of-flight sensing technology is its high range-to-power ratio. What this means is that, compared with other optical time-of-flight technologies, it can detect at a farther range with an equivalent amount of light.

This benefit can be leveraged in many different ways, depending on the target application.  Compared to a sensor integrating another optical time-of-flight technology, a sensor integrating Leddar technology can:

  • Have a longer detection range with an equivalent light output; or
  • Have a similar detection range with a lower light output.

Another way to leverage the high range-to-power ratio of Leddar is by using a diffuse light source instead of a collimated source. In this case, each detection element can cover a large area. Simple optics can then be employed to customize the emission and reception patterns for specific applications.

The second benefit of Leddar technology is its capability to detect targets in low-visibility conditions.  Since each measurement is formed from hundreds or even thousands of discrete light pulses, the likelihood that the technology is able to obtain reliable measurements under environmental conditions such as rain, snow, for or dust is very high.  This is particularly true when using a diffuse light source.

Finally, the third benefit of Leddar technology is its ability to resolve multiple targets with a single detector element.  Once again, this benefit can be fully exploited with a diffuse light source, where a small object may not fully occupy the field of view, and where the distance to background objects can be simultaneously measured.  Detecting multiple targets at once can represent significant added value and increased versatility for many applications. Even a single-element sensor can provide a high degree of spatial awareness.”
