Nitin Naresh writing in Inventiva notes, “The future of lidar is uncertain unless, as Voyant hopes to do, its price and size are reduced to fractions of their current values. As long as lidars are sandwich-sized devices that cost thousands, they won’t be ubiquitous — so Voyant has raised some cash to bring its smaller, low cost, more easily manufactured, yet still highly capable lidar to production.”
He explains, “When I wrote up the company’s seed round back in 2019, the goal was more or less to shrink lidar down from sandwich to fingernail size using silicon photonics. But the real challenge faced by nearly every lidar company is getting the price down.
Between a strong laser, capable receptor, and a mechanical or optical means of directing the beam, it just isn’t easy making something cheap enough that, like an LED or touchscreen, you can easily put several of them in a vehicle that costs less than $30K.
CEO Peter Stern joined the company just as COVID was getting started, and they were looking for a way to turn a promising prototype developed by co-founders Chris Phare and Steven Miller into a working and marketable product. After going back to basics they ended up with a photonics-based frequency-modulated continuous wave (FMCW) system (just go with it for now) that could be manufactured at existing commercial fabs.”
“Every other system is filled with a lot of expensive stuff — our vision is a mass-produceable chip, like anything else,” he said, and noted the lack of a powerful precision laser as a huge savings to cost and space. “What people use as a laser source generally costs a lot, needs assembly and calibration, there are lens issues… our laser sources are basically out of date, slightly refurbished datacom lasers the size of sesame seeds. These things cost like $5 each, the laser path costs $30, something like that.”
