Flash! Lidar's Next
Generation Arrives
by Lindsay Brooke
Technology solutions from new players and alliances are
poised to drive down cost.
Electronics engineers may best know what
typically happens in an emerging, rapidly moving
technology space. First, innovation: Start-ups bring
new solutions amid rounds of funding. Next is the
often-protracted shakeout period. OEMs evaluate
prototypes based on performance, quality, and cost;
the technologies are refined. Product announcements
are made. The " best way of doing it " becomes clearer.
Then come the Tier 1s, bringing their proficiency
in manufacturing and cost engineering. They take the
most valid architectures, knock most if not all the cost
out of them, and create a cost-effective solution, at scale.
Those dynamics are well along in automotive
lidar, observed Tom Jellicoe, leader of the autonomous driving team at TTP, an independent technology company in Cambridge, England. " There are
still new-device architectures coming out, " he noted.
" The industry has not settled on one type. There is
room for innovation. "
Of the 80 to 100 players in the mobility-perception arena who claimed to be " lidar companies "
before the pandemic, a more realistic total of around
two dozen are operating at various levels in 2021,
Jellicoe surmises. " None are large corporates poised to
dominate lidar any time soon, " Jellicoe, an opto-electronics expert, said. " But there are early signs of a

Continental
Continental's investment in California-based lidar maker AEye
brings the latter's +300-meter range and ability to detect small,
low-reflective objects at a distance of 160 meters, to a variety of
vehicle applications beginning 2024. Conti's own short-range,
high-resolution 3D Flash lidar enters production this year.
