A generational leap in LiDAR

A generational leap for automotive LiDAR, Spectrum HD Utilizes Barajas’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 L4 autonomy. Spectrum HD 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.

Designed for Automotive integration
Per-point Doppler velocity

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.

Interference immunity

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.

But 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.

Automotive durability

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 – lasting over 20 times the standard 10,000-hour lifespan. With the Spectrum-Scan™ platform, we’ve designed a robust and reliable system that requires less maintenance and is ready for commercial manufacturing at scale.
