About the Technology

 

LeddarSteer™ is a digital beam steering device (or DBSD) based on liquid crystal and polarization gratings which steers light to one of two deflection angles, depending on the polarization of the light.

  • Low scattering losses
  • High overall diffraction efficiency
  • Clear apertures exceeding 5 cm (current manufacturing process supports >15 cm)
  • Non-mechanical steering over a wide FoV (up to 120°) with sub-milliradian (mrad) precision
  • Low power consumption

Configurable Beam Steering

LeddarSteer divides the FoV into discrete tiles that can be assembled to create the complete frame, with or without a region of interest. These FoV configurations can be changed on-the-fly, depending on the vehicle’s speed or environment, to enable multiple ADAS and AD use cases to be fulfilled from a single LiDAR design.

Key Benefits

Leddar Ecosystem Logo

Higher range

  • Reduction of ambient light noise by receiver steering to a sub-segment of the FoV
  • Emitter steering enables higher collimation and peak power while maintaining eye safety and acceptable power consumption and thermal dissipation

Higher resolution

  • Emitter beam steering and/or receiver detector / detector array steering to sub-segments of the FoV
  • Optimized optical system
  • Reduced size and complexity (smaller FoV of the receiver and/or emitter subsystem)
  • Reduces the number of laser and detector elements needed

Scalable

  • Component can be designed into next gen of existing LiDAR designs
  • Compatible with a broad range of wavelengths (NIR, SWIR, MWIR, LWIR)
  • Up to 120° addressable steering

Adaptable

  • Compatible with a wide variety of LiDAR architectures

Reliable

  • Solid-state technology (no moving parts)
