The L2X digital lidar chip is the most powerful, highest performing chip we have ever designed, and it now powers all of Ouster's latest Rev 06 OS series scanning sensors.
Capable of counting up to 1 trillion photons per second, and outputting up to 5.2 million points per second , the L2X system-on-chip ("SoC") continues our journey along the Moore's Law curve by doubling the maximum data rate of our sensors. The L2X handles all the logic and signal processing on the sensor, and can now process both the strongest and second strongest returns of light for each pixel.
With the new L2X chip, industry-leading reliability, IP68/69K ruggedness, and full dual returns for even richer point cloud data, Ouster lidar delivers high-performance 3D perception and operations for all-weather, all-terrain conditions.
But first, a quick refresher of Ouster's core digital lidar technology and the critical role the L2X chip plays in sensor performance.
Our digital lidar architecture consists of a patented micro-optical system and a simple two-chip architecture that replaces the hundreds to thousands of discrete components commonly found in traditional analog lidar:
This simplified, integrated architecture is what enables us to deliver high-performance, reliability, and affordability today and our CMOS approach enables us to improve performance for years to come. Learn more about Ouster's digital lidar technology.
The L2X chip is the latest generation of our custom CMOS SoC, featuring a completely redesigned ASIC that enables full dual return processing capabilities and packed with extremely sensitive SPAD detectors capable of counting up to one trillion photons per second.
The L2X chip can process both the strongest and the second strongest returns of light from each pixel, doubling the total maximum number of points detected to 5.2 million points per second. This richer point cloud combined with our wide optical aperture further increases the accuracy of object detection, especially through environmental obscurants, such as dust, smoke, or even a chain link fence, and ensures machines operate safely and efficiently even in the toughest conditions.
By consolidating all the complexity of analog lidar onto a single silicon CMOS SoC, we dramatically improve performance while reducing costs over time. Ubiquitous technologies, such as computer processors and digital cameras, have all followed this same exponential improvement curve, known as Moore's Law. Our lidar technology's progression along Moore's Law curve delivers improvements to performance and cost that will help to make lidar ubiquitous.
Since launching the OS1-64 in 2018, we have already doubled the resolution of our sensors in just two years, from 64 to 128 channels with our L2 chip to develop the highest resolution digital lidar on the market. The L2X chip doubles our performance yet again, continuing along our CMOS SoC roadmap and demonstrating the exponential improvement potential of digital lidar.
Our newest hardware release, Rev 06, is powered by the L2X chip and equipped with the latest Firmware v2.2. Rev 06 introduces full dual return capabilities, doubles the signal processing power of our sensors, and is the most rugged and reliable sensor that we have ever built.
In real-world operating conditions - whether a robotaxi driving on a foggy morning or an excavator operating in a dusty construction zone - sensors must not only be mechanically reliable and robust, but also reliably output high-quality data. With the new L2X chip, IP68/69K ruggedness, and richer dual returns point cloud data, Ouster lidar delivers high-performance 3D perception in all weather and terrain conditions.
Rev 06, powered by the L2X chip, improves our sensors' ability to detect objects through obscurants such as rain, fog, dust, snow, and even thin delicate objects like a wired fence. By processing both the strongest and second strongest returns of incoming light, our sensors can more accurately detect objects that are partially obstructed behind external elements like foliage or smoke, behind thin delicate objects, and amidst obscurants like rain or fog.
Cameras simply cannot do this because they rely on receiving ambient light for each pixel, making them unable to detect even partially obstructed objects. In contrast, Ouster sensors utilize a large optical aperture and advanced digital processing via our L2X chip that enables our sensors to penetrate obscurants like rain, fog, and snow that would adversely affect the performance of cameras.
From operating autonomous mines in dusty open-pit mines in China, to vehicle-based mapping in the Canadian snow, to detecting pedestrians at outdoor intersections, Ouster sensors must reliably work all the time through the most rugged, thermally extreme environments and all terrain conditions.
Reducing sensor failure and downtime saves money and more critically, reduces safety risk from failed operations. This is why our sensors are designed to the highest standards of reliability and robustness, including IP68/69K and automotive-grade shock and vibe specifications. We continuously optimize our sensors through rigorous testing and failure analysis processes.
Additionally, our simplified digital lidar architecture dramatically reduces the points of failure from thousands, as seen in analog lidar, to just two chips and one moving part. This inherent digital lidar advantage, combined with our focus on reliability, results in the most rugged and reliable lidar sensors we have ever built.
The L2X chip is yet another major milestone along Ouster's product roadmap. We have completely redesigned the chip to dramatically boost processing power and double the maximum data output to provide even richer, dual returns point cloud data.
Combined with our industry-leading reliability and IP68/69K ruggedness, the latest Rev 06 sensors are the optimal choice for any outdoor application across automotive, industrial, smart infrastructure, and robotics.
