Unique Features of 4Sight M:

  • Up to 4 million points per second with horizontal and vertical resolution less than 0.1°
  • Ability to deploy multiple High-Definition Regions of Interest (ROIs) to enable targeting and classification of objects 10x to 20x more accurately than camera-only systems — while delivering the information 10x faster
  • Agile LiDAR allows for a user-defined library of deterministic scan patterns triggered by driving conditions and/or vehicle location
  • Detection of small, low reflective objects such tire fragments, bricks, or other road debris (10x50cm at 10% reflectivity) at ranges of over 120 meters
  • Detection through foliage and adverse weather conditions such as rain and fog through the use of dynamic range, full-waveform processing of multiple returns
  • Fuses 1550 nanometer (nm), solid-state agile MEMS LiDAR, an optional low-light HD camera, and embedded AI to intelligently capture data at the sensor level; enables the collection of 4x to 8x the information of conventional, fixed pattern LiDAR at a fraction of the energy
  • Combining the camera’s 2D pixels with the LiDAR’s 3D voxels creates Dynamic Vixels,™ a new data type which helps the AI refine the LiDAR point cloud around objects of interest
  • Designed and tested for solid-state performance and reliability; has proven in third-party testing to sustain mechanical shock of over 50G, random vibration over 12Grms (5-2000Hz)
  • Perception advancements made available through a software reference library
  • iDAR’s flexible system design enables seamless, cost-effective 360° coverage around the vehicle; seamlessly combine 4Sight As and 4Sight Ms to meet your specific requirements
  • A 1550nm Class 1 laser product per IEC 60825-1:2014

The 4Sight A Series is a game-changing, solid-state sensor family for ADAS applications.

Designed to address the need for modular, high-performance sensors based on the iDAR platform, the 4Sight A Series features the industry’s only software definable LiDAR and industry-leading ADAS performance. The 4Sight A Series includes six layers of interference mitigation, anti-spoofing technology, and is under ASIL-B functional safety certification — ensuring it meets the automotive industry’s stringent safety standards.

Unique ADAS Offerings at Design Time:

  • Agile LiDAR enables user’s choice of deterministic scan patterns catered to specific use cases and applications, such as collision avoidance and automatic emergency braking (AEB).
  • Feature-specific Fixed Regions of Interest (ROIs) designed to detect threats from various locations.
  • Optional camera integration cues LiDAR for additional environmental data and sensor redundancy.
  • Perception advancements made available through a software reference library.
  • Windshield, grill, and other discreet vehicle integration options.
    SWaP optimized.
  • FuSa/SOTIF compliant for signal path ­­— providing necessary determinism for testing and validation.
  • Option to non-deterministically scan without breaking the FuSa signal path — reducing the potential unknown, unsafe conditions as required for SOTIF/ISO2144.
