New LiDAR Sensor Delivers Automotive Solid-State Reliability

Available in July, 2020, 4Sight provides automotive-grade ruggedness combined with software-definable range of up to 1,000 meters and 0.025° resolution at a lower cost than most current LiDAR sensors By DA Staff / 09 Jun 2020

AEye, Inc has released 4Sight, a new sensor family built on its Intelligent Detection and Ranging (iDAR) platform.

Debunking previous assumptions that high performing long-range 1550nm LiDAR could not achieve both solid state reliability and lower cost, according to AEye, 4Sight delivers on all three – performance, reliability and price.

The first 4Sight sensor to be released in July 2020 is the 4Sight M, which is designed to meet the diverse range of performance and functional requirements to power autonomous and partially automated applications. 

The 4Sight family of sensors has been developed and tested over the last 18 months in conjunction with a wide range of customers and integrators in automotive, trucking, transit, construction, rail, intelligent traffic systems, aerospace and defense markets. 4Sight leverages the complete iDAR software platform, which incorporates an upgraded visualizer (which enables the modeling of various shot patterns) and a comprehensive SDK so it is fully extensible and customizable.

“The primary issue that has delayed broad adoption of LiDAR has been the industry’s inability to produce a high-performance deterministic sensor with solid state reliability at a reasonable cost,” said Blair LaCorte, President of AEye. “We created a more intelligent, agile sensor that is software definable to meet the unique needs of any application – the result is 4Sight.”

Some of the features of the 4Sight M are:

LiDAR Performance

  • Software definable range optimization of up to 1,000 meters (eye- and camera-safe)
  • Up to 4 million points per second with horizontal and vertical resolution less than 0.1°
  • Instantaneous addressable resolution of 0.025°

Integrated Intelligence

  • Library of functionally-safe deterministic scan patterns that can be customized and fixed or triggered to adjust to changing environments (highway, urban, weather, etc.)
  • Integrated automotive camera, boresight aligned with AEye’s agile LiDAR – instantaneously generating true color point clouds. Parallel camera-only feed can provide cost-effective redundant camera sensor.
  • Enhanced ground plane detection to determine topology at extended ranges

Advanced Vision Capabilities

  • Detection and classification of objects with advanced perception features such as intraframe radial and lateral velocity
  • Detection through foliage and adverse weather conditions such as rain and fog through the use of dynamic range, full-waveform processing of multiple returns
  • Detection of pedestrians at over 200 meters
  • Detection of small, low reflective objects such tire fragments, bricks or other road debris (10x50cm at 10% reflectivity) at ranges of over 120 meters


  • Shock and Vibration – designed and tested for solid-state performance and reliability. 4Sight has proven in third-party testing to sustain mechanical shock of over 50G, random vibration over 12Grms (5-2000Hz), and sustained vibration of over 3G for each axis.
  • Automotive-grade production:
    • Automotive-qualified supply chain utilizing standard production processes and overseen by global manufacturing partners
    • Designed for manufacturability using a simple solid-state architecture consisting of only 1 scanner, 1 laser, 1 receiver, and 1 SoC
    • Common hardware architecture and software/data structures across all fully autonomous to partially automated applications (ADAS) – leveraging R&D and economies of scale


  • 4Sight can be configured for high-volume Mobility applications with SOP 2021 at an estimated 2x-5x lower price than any other high-performance LiDAR, additionally for ADAS applications with SOP 2023 4Sight is designed to be priced 1.5x to 3x lower than any other long or medium range LiDAR
  • 4Sight series production packaging options include roof, grill, and behind the windshield, software optimized depending on the placement

“In my work with automotive OEMs, the value delivered by the 4Sight sensor surpasses anything I have seen in the automotive industry,” said Sebastian Bihari, Managing Director at Vektor Partners. “By starting with understanding the data a perception system needs, AEye has developed a simpler more responsive design for efficiently capturing and processing perception data. In doing this, 4Sight establishes standards for the industry that will take years for others to achieve.”

4Sight’s groundbreaking system attributes such as time-to-detect, agile scanning, shot energy optimization, power optimization of returns, and boresight camera/LiDAR data generation, greatly reduces the processing and bandwidth typically required for full perception stacks. When implemented in a vehicle, AEye expects 4Sight sensors to be nearly power neutral in relation to a vehicle’s perception stack power budget.
