way - like per-pixel depth. " Operating in
the SWIR portion of the spectrum is a
huge advantage, Bakal noted, " because
we are shooting a very high peak-power
pulse that's illuminating the scene for a
very long range, over 200 meters... really
200 meters, not marketing.
With this kind of system, you don't
need lidar. You have image in any weather
and lighting condition, you have depth
capability in any weather and lighting
condition, and all that in a product that is
TriEye's SWIR technology could bring enough
requisite data to AV sensor stacks to eliminate
the need for lidar.
from reaching mass-market volumes to
prevent more accidents.
TriEye's solution is what it calls SEDAR
(spectrum-enhanced detection and ranging),
which it claims outperforms any lidar
system on the market in terms of cost and
performance. Bakal explained that the
TriEye innovation is its proprietary CMOS
sensor, which it developed after nearly a
decade of research, which it combines
with its proprietary illumination source
that operates (like lidar) outside the visible
spectrum. Both components were
designed to meet high-volume manufacturing
requirements from day one.
" The way we operate and build depth
is by illuminating the scene in very short
pulses, a kind of code that we know, "
Bakal explained. " Based on the code and
how it interacts with the surroundings, we
can extract the depth in a deterministic

very low cost compared to any lidar.
" Once you provide a system that is
not using just your own vehicle lighting,
that's where the real breakthrough
comes, " Bakal said, adding also the advantage
of being " camera " -based for
object recognition.
" We are leveraging the existing and the
proven, the pre-trained algorithms that
reduce dramatically the time and cost of
the development cycle that leads to easy
integration to the existing ADAS and AV
system. If you want to add radar or not,
this will be the question. "
When will this breakthrough SWIR
tech appear on production vehicles?
TriEye announced a collaboration with
Tier 1 Hitachi Astemo in January 2022,
and Bakal claimed they are already embedded
in current development cycles.
" I can say that we are in a few integration
paths as of today, [and] as you are
aware, the integration cycle into a vehicle
is a few years' path, " he disclosed.
" In the next couple of years, you will
see vehicles equipped with the TriEye
solution. We expect this to happen, I
would say, three years from now. "
