Lidar camera uses “world’s smallest micro-mirror” for continuous field of view scanning

Continuous laser scanning across the entire field of view is achieved in the Intel RealSense Lidar camera L515, using a MEMS mirror developed by STMicroelectronics.

The lidar camera is 61mm diameter and 26mm high (2.4 inches and 1.02 inches respectively), or the size of an ice hockey puck. The micro-mirror enables continuous laser scanning across the entire field of view. In combination with a custom photodiode sensor, the RealSense Lidar Camera L515 renders a 3D depth map of the entire scene.

The camera provides high resolution scanning for industrial applications such as robotic arms for bin picking, volumetric measurements, logistics and 3D scanning.

The second-generation micro-mirror delivers 30 frames per second and a field of view of 70 degrees by 55 degrees, for 3D scanning and detection applications.

The L515 camera uses the scanning capabilities of ST’s MEMS to deliver high-resolution depth with no interpolated pixels, together with the ability to control the field of view, and provide close to zero pixel blur driven by the low 50nS exposure time, continued ST.

“Intel RealSense technology has been used to develop products and solutions for use in Robotics, Logistics, Scanning and other computer vision applications.  The Intel RealSense LiDAR Camera L515 using ST’s micro-mirrors delivers unparalleled precision and is the world’s smallest high-resolution Lidar depth camera, making it suitable for a variety of use cases,” said Sagi BenMoshe, chief incubation officer, corporate vice president and general manager, Emerging Growth and Incubation Group at Intel.

Intel RealSense technologies are reshaping the future by equipping devices with the ability to see, understand, interact with and learn from their environment, says Intel. RealSense provides a wide variety of vision-based solutions, from the world’s smallest high-resolution lidar camera to low power, platform-agnostic stereo depth cameras, as well as customisable software. Intel RealSense has applications in robotics, 3D scanning, facial authentication, measurement and logistics.

ST Microelectronics is an independent device manufacturer, working with more than 100,000 customers and thousands of partners to design and build products, solutions, and ecosystems that enable smarter mobility, more efficient power and energy management, and the wide-scale deployment of the IoT and 5G technology.
