Baraja Lifts Curtain on Spectrum-Scan Lidar for Autonomous Vehicles

31 July 2018

Baraja has unveiled Spectrum-Scan lidar (light detection and ranging), which uses prism-like optics and shifting wavelengths of light to create powerful eyes for autonomous vehicles, giving those vehicles unprecedented data and clarity of vision, a requirement for safe, fully-autonomous driving.

Spectrum-Scan lidar represents an entirely new category of lidar, pairing a wavelength-tunable laser with prism-like optics. This innovation addresses the scalability, reliability and performance issues that have challenged automakers, rideshares and tech behemoths as they race toward a Source: BarajaSource: Barajafully-autonomous future.

Spectrum-Scan technology enables Baraja lidar to deliver high performance and long range in a system built from simple industrialized components, which greatly improves automotive reliability versus competing technologies. With a flexible, modular design that simplifies integration into the vehicle, Baraja lidar allows autonomous vehicles to smartly control and adjust scan patterns in real-time to adapt to complex, dynamic road conditions.

Solving the Lidar Challenge

Traditional lidar scans the roadway by physically rotating lasers or using moving mirrors to steer the light using microelectromechanical systems (MEMSs). These moving parts have unresolved reliability problems in vehicles due to constant vibration and shock. Delicate components fail or require costly over-engineering to house and protect.

These legacy scanning methods inject cost, reliability and performance issues, and contribute to the unwieldy appearance and vehicle integration difficulties of existing lidar solutions. These limitations have become a serious bottleneck to the mass deployment of self-driving cars.

Baraja’s compact, modular “eyes” connect via fiber optics and deliver the high level of performance demanded by the autonomous vehicle industry using off-the-shelf components—like optical-grade silica-glass found in every smartphone camera and telecom-grade lasers that power the internet. These components maximize automotive reliability and the ability to mass produce the technology for fleets while enabling long-term cost benefits.

Designed for Reliability and Scale

In developing Spectrum-Scan lidar, Baraja designed for the end goal: building lidar that can realistically be integrated into vehicles. By addressing the need for high-volume scalability, manufacturability and reliability, Baraja has guided the product development with a design-for-manufacture (DFM) approach.

“After spending years in stealth, iterating behind closed doors with OEMs and other high-profile pioneers in the autonomous vehicle space, we are confident that we have built a high-performance lidar system, one that addresses many of the challenges facing the autonomous vehicle industry today,” said Cibby Pulikkaseril, Baraja co-founder and CTO. “Automakers and tech companies want to put fleets of safe and reliable autonomous vehicles on the road. Spectrum-Scan lidar will help them get there faster.”

Baraja is headquartered in Sydney, Australia, with offices in San Francisco and China. The company is currently expanding throughout Asia and Europe. Baraja is backed by funding from Sequoia China, Blackbird and other investors.

Baraja’s Spectrum-Scan lidar is available now.
