OPA-based solid state lidar with 100 m range demonstrated

03 August 2021

Quanergy Systems Inc., a developer of smart lidar solutions for automotive and internet of things applications, has completed a successful driving demonstration of its S3 series lidar. The solid state lidar sensor is based on industry-first optical phased array (OPA) technology and a scalable complementary metal-oxide semiconductor silicon manufacturing process for cost-effective, mass-market production.

The demonstration was conducted in partnership with Zero Electric Vehicle Inc., an innovative sustainable Source: Quanergy Systems Inc.Source: Quanergy Systems Inc.energy company that provides fleet electrification and electric vehicle platforms for companies looking to maximize their existing assets while transitioning to electric transportation.

For this test, a solid-state lidar test platform with single scanning beam was mounted on a vehicle, along with additional cameras to facilitate visual viewing. The test vehicle followed a target vehicle driving in bright sunlight at a variety of ranges -– from a close proximity to a distance of 100 m -– while maintaining safety at all times. A target with 10% reflectivity was chosen to simulate very difficult-to-detect objects.

The S3 series LiDAR sensor is designed to meet the most stringent automotive requirements for object detection and collision avoidance. The sensor’s unique electronic beam steering without any moving parts offers immunity to shock and vibration, and provides over 100,000 hours mean time between failures.
