The latest stealth autonomous vehicle start-up to come out of hiding is Sense Photonics offering “flexible” flash lidar. The main advantages that this provides is the ability to locate the sensor on a curved surface and the ability to achieve a much wider field of view.
From an article in Tech Crunch by Devin Coldewey
Lidar is a critical part of many autonomous cars and robotic systems, but the technology is also evolving quickly. A new company called Sense Photonics just emerged from stealth mode today with a $26M A round, touting a whole new approach that allows for an ultra-wide field of view and (literally) flexible installation.
Still in prototype phase but clearly enough to attract eight figures of investment, Sense Photonics’ lidar doesn’t look dramatically different from others at first, but the changes are both under the hood and, in a way, on both sides of it.
Early popular lidar systems like those from Velodyne use a spinning module that emit and detect infrared laser pulses, finding the range of the surroundings by measuring the light’s time of flight. Subsequent ones have replaced the spinning unit with something less mechanical, like a DLP-type mirror or even metamaterials-based beam steering.
That’s what Sense has created, and it claims to have avoided the usual shortcomings of such systems — namely limited resolution and range. Not only that, but by separating the laser emitting part and the sensor that measures the pulses, Sense’s lidar could be simpler to install without redesigning the whole car around it.
I talked with CEO and co-founder Scott Burroughs, a veteran engineer of laser systems, about what makes Sense’s lidar a different animal from the competition.
“It starts with the laser emitter,” he said. “We have some secret sauce that lets us build a massive array of lasers — literally thousands and thousands, spread apart for better thermal performance and eye safety.”
