Our Spectrum-Scan™ system is a unique architecture using wavelength-tunable lasers within the 1550nm C-band to scan the environment. This design innovation means we’ve removed the most expensive, bulky and failure-prone components in a LiDAR system – mechanical scanning in the fast axis. To ensure reliable, accurate, repeatable performance over automotive shock, vibration, thermals and lifetime requirements is extremely challenging for traditional LiDAR, which is why Baraja’s solid-state fast axis is such a game changer. Not only does it solve this challenging automotive reliability problem, but it also comes with additional performance and pointcloud improvements and lays the core foundation for high performance, miniaturized LiDAR for automotive reliability.
Baraja’s Spectrum-Scan™ LiDAR is an elegant system that is completely solid-state in the fast axis to mitigate key failure modes. We started from scratch, with full automotive integration at the core of our approach by refracting light through a prism to scan in one axis at more than a million times per second, with no-moving-parts. This allowed us to remove the most expensive, bulky and failure-prone components of any LiDAR system – mechanical scanning in the fast axis.
By taking a radically different approach to scanning we’ve achieved breakthroughs in performance and precision. To overcome the architectural flaws of other legacy LiDAR technologies and meet our benchmarks, other LiDAR makers will have to completely rethink their solutions. Because we’ve solved the fundamental challenges of LiDAR scanning, our core technology won’t need to change. We have a clear roadmap to fit our sensor onto a single chip, unlock the benefits of semiconductor manufacturing, miniaturize our product and lower the overall cost to meet automotive requirements.
Long range perception is paramount for safe autonomous driving, but sensitivity alone isn’t enough, it requires data that leads to accurate detection – what we call ‘effective range’. Our Spectrum-Scan™ system combines improvements in sensitivity, resolution, beam divergence, accuracy and precision to ensure you can classify even small objects at maximum range, meaning safer autonomous driving from city streets to country highways.
Baraja LiDAR’s architecture leverages the 1550nm wavelength band, otherwise known as the C-band, allowing for increased transmit power which is higher when compared to the 900nm wavelength band and enables an incredible increase in maximum range from 76m to over 200m on the same low reflectivity. In addition to the performance benefits, 1550nm light is less hazardous to the human eye than 900nm.
