LeddarTech releases its LeddarSteer automotive-grade, solid-state digital beam steering technology for LiDAR sensor developers

LeddarTech® is pleased to announce the official release of LeddarSteer™, a digital beam steering solution designed for LiDAR smart sensor developers and Tier 1-2 automotive suppliers.

Digital beam steering refers to changing the direction of laser pulses in a LiDAR. Using a stack of alternating liquid crystal cells and polarization gratings enables to steer light at different angles at a specific wavelength in order to augment a LiDAR field of view while maximizing its performance, allowing digital beam steering for LiDAR to be achieved.

LeddarSteer digital beam steering offers a myriad of benefits to LiDAR smart sensor developers and Tier 1 and 2 customers, including:

  • Software-controlled on-the-fly adjustment
    • Frame-by-frame adjustment
    • Preset or customized configuration
    • Easy setup and interface
    • Voltage-controlled steering
  • Multiple LiDAR applications
    • Compatible with a wide range of LiDAR architectures
    • Enables one LiDAR to address multiple use cases
    • Field of view adjustable for various actions, including turns, exits, lane changes and slopes
    • Same LiDAR for highway and city driving
    • Reduces the number of sensors, generating cost savings
  • Automotive-grade solid-state technology, resulting in a significantly higher MTBF (mean time between failures)

LeddarSteer can be seamlessly integrated into an existing LiDAR to expand the field of view or integrated into new LiDAR development. The solution provides an enhanced signal-to-noise ratio by concentrating laser power on a small region of interest while reducing the size, cost and complexity of LiDAR components whilst maintaining or increasing the pixel count and resolution.

“For well over a decade, LeddarTech has been a leader in developing sensing solutions that enable our customers to deliver high-performance ADAS and AD sensors,” stated Mr. Charles Boulanger, CEO of LeddarTech. “LeddarSteer is the only digital beam steering smart component designed for mass production with the flexibility, reliability, cost, size and performance required by the most demanding 3D sensing applications and supported by standard automotive manufacturing process,” concluded Mr. Boulanger.
