Intel has developed a LiDAR system based on a tiny micro-mirror, developed by STMicroelectronics, to provide high-resolution scanning for industrial applications such as robotic arms and 3D scanning.

Built into the Intel RealSense LiDAR Camera L515, the ultra-small dimensions of the micro-mirror contribute to the LiDAR camera’s size - it measures just 61mm x 26mm. The micro-mirror enables continuous laser scanning across the entire field of view and, in combination with a custom photodiode sensor, the RealSense LiDAR Camera L515 renders a 3D depth map of the entire scene.

“With 30 frames per second and a field-of-view of 70° by 55°, ST’s 2nd-generation micro-mirror continues to set the bar for 3D scanning and detection applications,” said Benedetto Vigna, President Analog, MEMS and Sensors Group, STMicroelectronics. “Continuing the long-term supply relationship for micro-mirrors with Intel demonstrates our efforts to leverage our long-lasting leadership in MEMS to meet the demanding technical and supply needs of our customers.”

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

“Intel RealSense technology has been used to develop products and solutions for use in Robotics, Logistics, Scanning and other computer vision applications. The RealSense LiDAR Camera L515 using ST’s micro-mirrors is able to deliver unparalleled precision and is the world’s smallest high-resolution LiDAR depth camera, making it suitable for a variety of use cases,” added Sagi BenMoshe, Chief Incubation Officer, Corporate Vice President and General Manager, Emerging Growth and Incubation Group at Intel.
