The LCA3 SoC is the core of Multi-Channel LIDAR Sensors for object detection in automotive applications. It uses the Time-of-Flight (ToF) principle of light pulses reflected by one or more objects. LeddarTech’s LCA3 SoC is a LiDAR System-On-Chip (SoC), which enables rapid, high-volume deployment of solid-state 3D LiDARs that meet the automotive industry’s stringent performance, cost and reliability requirements. The LCA3 SoC integrates a powerful, proven, patented LiDAR technology into a low-cost SoC. The LCA3 SoC is supplied for the mass production of various customized solid-state LiDAR solutions, which are deployed by automotive OEMs for semi- and fully autonomous driving applications in production vehicles.

Product function:
The LCA3 LeddarEngine is designed to be the core of a Time-of-Flight LiDAR. It measures the time difference between the emission of a laser pulse and its return to the sensor, after being reflected by an object. The Time-of-Flight measurement is made after the acquisition by the LeddarCore SoC (through photodiodes) and the processing of the returned signal by the LeddarSP processing Library.
Target Application:
LCA3 SoC supports several LiDAR application scenarios for object detection with dedicated control algorithms for both laser triggering and data acquisition: 2D and 3D Flash Applications, 3D Scan MEMs Mirror and Mirror Master Application.
