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 steering 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: Frame-by-frame adjustment; Preset or customized configuration; Easy setup and interface; Voltage-controlled steering; 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.
