4Sight A

A game-changing sensor family optimized for ADAS applications.

Software-configurable and built on a modular architecture, the 4Sight™ A series is easily customizable to address the specific design requirements for multiple OEMs. Manufactured and updated by our Tier 1 partners for the entire lifecycle of the vehicle, the 4Sight™ A series features industry leading, long-range ADAS performance, designed to address the need for high-performance applications. 4Sight™ A is built on 1550nm, solid-state, adaptive LiDAR and AEye’s unique, patented, advanced MEMS.

The 4Sight™ A’s software configurability enables the creation of deterministic scan patterns and Regions of Interest (ROIs) that can be defined for various ADAS applications, use cases, or driving scenarios, such as highway and urban, without any hardware replacement. The 4Sight™ A 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 Features of 4Sight™ A (includes all features of 4Sight™ M optimized for ADAS):

  • Adaptive 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
  • Priced 1.5-3x lower than other long or medium range LiDAR for ADAS applications with SOP 2023
  • Option to non-deterministically scan without breaking the FuSa signal path — reducing the known unknowns required for SOTIF/ISO2144

Flexible Placement Options

Flexible Sensor Placement Options

iDAR™’s modular architecture enables seamless, cost-effective 360° coverage around the vehicle.

  • Configurable for high-volume Mobility applications with SOP 2021 at a 2-5x lower price than other high-performance LiDAR
  • Production packaging options include roof, grill, and behind the windshield (software optimized depending on the placement)
