A generational leap for automotive LiDAR, Baraja Spectrum-Scan™ technology now with per-point doppler velocity.
Spectrum HD25 utilizes Baraja’s proprietary Spectrum-Scan™ solid-state scanning mechanism, bringing per-point Doppler velocity without the traditional trade-offs faced by FMCW LiDAR systems to help bridge critical gaps in achieving full autonomy. Spectrum HD25 delivers this incredible performance in a package small enough for discreet vehicle integration and meets the automotive standards and cost targets for high volume commercial deployment.
By measuring the Doppler shift of returning light for each point in the pointcloud we can detect whether an object is in motion and calculate its speed. This data can be used to detect movement at a distance, such as a pedestrian stepping out of a stationary crowd into the road. And while other LiDAR relies on software processing to infer this information, our measurement is built into hardware.
Traditional LiDAR systems are vulnerable to interference from external light sources, in particular other LiDAR sensors, a major obstacle to safely putting autonomous vehicles on the road.
The Spectrum-Scan™ platform is the first LiDAR with a unique built-in immunity to all interference. A signal would have to match the exact timing, angle, wavelength and encoding to interfere with our system. This multi-layered protection means no more blind spots in perception and enhanced safety that’s ready for tomorrow’s sensor-filled world.
Our core innovation of solid-state scanning in the fast axis, using only a laser and a prism, means we’re a generation ahead in terms of performance and reliability. By removing the mechanical components most prone to failure, our sensors easily exceed the stringent automotive requirements for shock resistance and longevity.
