AEVA’s 4D LiDAR technology

4D LiDAR Sensors on a Chip

Aug. 10, 2021
Aeva will integrate its mapping sensors with Nikon’s industrial measurement tools.

A collaboration announcement between Aeva Technologies and Nikon Corporation marks a moment of growth, as they expand the use of LiDAR technology into the industrial automation, metrology and manufacturing space.

Aeva, a Mountain View, Calif.-based LiDAR company, will leverage its unique perception technology with micron-level measurement capability and Nikon’s high precision industrial automation and metrology capability. The collaboration to develop next generation industrial solutions marks the first time Aeva’s 4D LiDAR technology is used outside of self-driving cars.

“We’re excited to work closely with a leader like Nikon in an established market with massive growth potential as we accelerate our expansion into industrial applications, targeting product release in 2025,” said Soroush Salehian, co-founder and CEO at Aeva.

Salehian said his company’s LiDAR chip architecture, or Frequency Modulated Continuous Wave (FMCW) 4D LiDAR, has the potential to upend the growing industrial automation industry. The software stack will enable the company to scale into such industries as industrial robotics, consumer electronics and healthcare. The solution is smaller and cheaper than comparable industrial sensors, he said.

Light Detection and Ranging

LiDAR stands for “Light Detection and Ranging.” LiDAR sensors measure the time it takes for the light to bounce off objects. The distance between the object and the sensor is measured and creates a map of an environment. Legacy or time-of-flight LiDAR measures only depth and reflectivity. FMCW LiDAR streams continuous beams of light to objects in an environment and measures velocity, depth reflectivity and inertial motion.

Salehian explained that Aeva’s 4D LiDAR-on-chip measures distance as well as instant velocity of every point on objects without losing range. The FMCW technology operates at fractions of the optical power required at this range. A notable differentiator has been the ability to integrate multiple beams on a single chip, Salehian said. Each beam can measure more than 2 million points per second at distances beyond 300 m.

The technology already plays a pivotal role in the emerging automated driving industry, particularly for advanced driver assistance and autonomous driving systems. Aeva developed its technology for OEM and automotive firms and has received strategic investments from Porsche SE, and has secured relationships with large Tier 1 automotive suppliers. In January, AEVA collaborated with DENSO, a global mobility supplier of advanced automotive technology for automakers, to bring AEVA’s 4D LiDAR technology to the mass vehicle market.
