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

Tue, Mar 09, 2021

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.

SiPM array is qualified for automotive lidar use

Tue, Mar 02, 2021

Lidar capabilities have been added to ON Semiconductor’s intelligent sensing portfolio, with the addition of the RDM-series silicon photo-multiplier (SiPM) array. The ArrayRDM-0112A20-QFN is the first automotive-qualified SiPM product in the market, claims ON Semiconductor.

The monolithic (1 X 12) array of SiPM pixels, enables high sensitivity to near-infra red (NIR) light to achieve 18.5 per cent photon detection efficiency (PDE) at 905nm. The high internal gain of the SiPM allows sensitivity down to the single photon level, which, combined with the high PDE, detects the faintest return signals for a longer distance range, even with low reflective targets, says ON Semiconductor.

SiPM technology has become the sensor of choice for depth sensing applications. They can deliver the highest signal-to-noise performance for long distance ranging in bright sunlight conditions. They also have low supply biases and low sensitivity to temperature changes, making them suitable upgrades for systems that use legacy avalanche photodiodes (APDs). The high volume CMOS process production contributes to the low detector cost, adds ON Semiconductor.

Lidar is used in vehicles to improve safety and advanced driver assistance systems (ADAS), as well as for fully autonomous driving use cases, such as robotic transportation, to safely navigate the environment in real time.

The ArrayRDM-0112A20-QFN’s high PDE allows lidar systems supporting these functions demonstrated a distance range of over 300 meters. The greater distance gives vehicles more time to respond.

The ArrayRDM-0112A20-QFN is AEC-Q102 qualified and developed in accordance with IATF 16949.

ON Semiconductor supplies semiconductor-based solutions, offering a comprehensive portfolio of energy efficient, power management, analogue, sensors, logic, timing, connectivity, discrete, SoC and custom devices. The company’s products are used by engineers in automotive, communications, computing, consumer, industrial, medical, aerospace and defence applications.
