Lumotive Says It’s Got a Solid-State Lidar That Really Works

Lumotive, a startup in Bellevue, Wash., has a compact, long-range lidar sensor that is at least as capable as the best machines from its rivals but smaller, cheaper to make, and more robust. The device can thus see far without having to turn up the brightness. That’s important because the sensor works at 905 nanometers, an eye-sensitive wavelength the company chose because it works with silicon. Lumotive shines a beam on a liquid-crystal “metamaterial” that has tiny tunable components, each of which can be used to slow down one part of the laser beam with respect to another part.
