ST micro-mirror deployed in Intel LiDAR camera

Semiconductor company STMicroelectronics has collaborated with Intel on the development of a tiny MEMS mirror, enabling spatial scanning of an environment. Intel developed a LiDAR system based on this micro-mirror, providing high-resolution scanning for industrial applications such as robotic arms for bin picking, volumetric measurements, logistics and 3D scanning.

Built into the Intel RealSense LiDAR Camera L515, the small dimensions of the ST micro-mirror contribute to the LiDAR camera’s hockey-puck size (61 mm diameter x 26 mm height). The micro-mirror enables continuous laser scanning across the entire field of view. In combination with a custom photodiode sensor, the camera renders a 3D depth map of the entire scene.

“With 30 frames per second and a field of view of 70° x 55°, ST’s second-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 never-ending efforts to leverage our long-lasting leadership in MEMS to meet the demanding technical and supply needs of our customers.”

The L515 leverages 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 close to zero pixel blur driven by the low 50 nS exposure time.

“Intel RealSense technology has been used to develop products and solutions for use in robotics, logistics, scanning and other computer vision applications,” said Sagi BenMoshe, Chief Incubation Officer, Corporate Vice President and General Manager, Emerging Growth and Incubation Group at Intel.

“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.”
