Ouster announces solid-state digital lidar sensor

New solid-state lidar sensor targets ADAS and industrial automation and puts Ouster’s digital lidar on a path to a $100 lidar sensor

Ouster announced a new solid-state lidar sensor based on its digital lidar architecture. The new ES2 sensor will be the first true solid-state, high-resolution, long-range digital lidar sensor. With a $600 expected price for automotive production programs with SOP 2024 and a 200+ meter range, Ouster’s new sensor offers a low-cost option for Advanced Driver Assistance Systems (ADAS) and industrial automation.

Solid-state digital lidar

The addition of a solid-state sensor is the natural extension of Ouster’s digital lidar approach. Leveraging the proven digital lidar architecture from its OS series spinning sensors, Ouster transferred the same core technology to design a true solid-state lidar sensor with no moving parts.

The ES2 sensor uses “electronic scanning” to sequentially fire an array of over ten thousand lasers printed onto a single chip. These lasers are paired with a custom digital detector array capable of counting trillions of individual photons every second. These laser and detector arrays are the same core technology used in Ouster’s OS series spinning lidar sensors, as well as numerous consumer devices such as the iPhone and iPad Pro. With tens of thousands of lasers on the chip, each fixed on a different point in the field of view, no moving parts are required to reach the range, field of view, and resolution targets of high-performance autonomy customers.

The similarity of Ouster’s product lines is a distinct advantage, as is their reliance on digital components shared by consumer electronic device supply chains. With manufacturing, calibration, and validation already running at scale for its OS series spinning sensors, Ouster’s ES2 solid-state sensor will be built on the same high-volume production line already operating at its overseas manufacturing facility.

Built to fit ADAS and higher-level autonomy performance targets, Ouster’s ES2 sensor will debut with a maximum range of over 200 meters on a 10% reflective surface.

From the beginning, Ouster designed the ES2 sensor to meet and exceed automotive standards for performance, reliability, and longevity. Its true solid-state design is an advantage: with no moving parts, the sensor is inherently less complex and fragile than other semi-solid state designs that rely on micro-mechanical spinning mirrors or other physical scanning mechanisms.

Ouster’s ES sensors are likely to be the safest, most reliable sensors on the market due to their true solid-state, digital design. The sensors will be fully certified for cybersecurity, shock & vibration, thermal cycling, ingress protection, and more according to the most stringent industry standards, including ISO 26262 (ASIL-B), SIL-2, and ASPICE.

Available in 2022

Development of the ES2 sensor is underway at Ouster’s San Francisco headquarters, and they plan to deliver samples of the product to key customers and partners in 2022. Volume production will commence in 2023, with a PPAP schedule that fits with SOP 2024 validation timelines for larger automotive and ADAS applications. In addition to automotive and ADAS applications, Ouster also plans to make the ES2 available for key customers in the robotics, industrial automation, and smart infrastructure industries.
