New Chip Technology to Improve Lidar Sensor Capabilities

A new advanced system-on-chip offers better signal processing to improve range detection in its digital lidar sensors.

FREMONT, CA:The new advanced L3 system-on-chip brings performance benefits to its sensor solution. It  uses back-side illumination, a method of arranging imaging elements to increase the amount of light captured to improve low-light performance. This new technology introduces back-side illumination to lidar sensors in the digital camera industry.

This technology combines the various aspects of analogue lidar onto a single silicon chip to improve performance and system costs. This chip is integrated into various lidar sensors to enable visibility and range detection in various use cases. The L3 brings a transformation capability improvement across the entire customer set and new capabilities to existing product lines and impacting customers.

More Processing Power Enhances Object Detection

The new L3 chip includes a wide range of transistors and a maximum computational power of 21.47 GMACS offering better digital signal processing and additional customer performance features. With the chip’s improved on-chip processing capabilities, approximately 10 trillion photons per second can be processed, and 5.2 million points per second can be generated.

Furthermore, with the improved light-collecting capability, a longer detection range is possible with this new system. It can cover four times the area and see two times further out in all directions. This is useful for various applications such as surveying, drones, robotics, and collision avoidance systems.

New Sensing Capabilities

The new chip is more precise and accurate due to its higher sensitivity. This facilitates millimetre precision measurements of objects in every direction. Customers can now use the technology for collision avoidance or navigation and surveying. In an agricultural machine application, this technology allows for system development by looking at features on plants to understand phenotyping or assessing a plant’s traits and picking fruit out of a tree.

In construction applications, customers can use the enhanced sensor technology to develop a survey-grade digital twin, which is millimetre accurate while the machine operates on the job site. The technology is unveiling new capabilities with the sensors. The primary goal of lidar as a sensing technology is to provide visibility as far as possible with greater accuracy, precision, and sharpness.

In addition to this system, new scanning sensors are introduced, offering improved mapping capabilities, more accurate obstacle detection, and safer autonomous operation in indoor and outdoor sites. This had approximately 95 per cent automotive-grade components ensuring its durability in various applications. Upgrades to the sensors enhance maximum operating temperature, reduce power draw, and multiply the sensor’s resistance to shock and vibration without adding weight.
