The reflections are used to create a 3D point cloud, which an onboard computer then uses to make an animated 3D representation. LiDAR is being incorporated into a new development called Pre-Scan whereby a laser scans the road surface to enable the wheel’s individual suspension to be adjusted. In the US, self-driving cars have already hit the roads of California, Texas, Arizona, Washington, Pennsylvania, Michigan although their mobility is restricted to specific test areas and driving conditions.
In February the Munich headquartered high-tech company, Osram Opto Semiconductors GmbH, presented its new infrared laser for LiDAR near-field applications, the SPL DP90_3, that it says could bring autonomous driving one step closer.
The component was specially developed for high-resolution near-field detection in LiDAR systems. It introduces a new single-channel pulse laser that is characterized above all by its improved beam quality and its particularly compact dimensions. The space-saving footprint of just 0.3 mm x 0.6 mm allows system manufacturers to incorporate extremely compact designs.
“With an optical output of 65 watts at 20 A, the component not only has an absolutely unique selling point on the market but is also ideal for capturing the immediate vehicle environment and thus ensures high-resolution images for the downstream systems,” said the company.
In January, the San Francisco headquartered builder of high-resolution LiDAR sensors for autonomous vehicles, robotics and drones, Ouster Inc., introduced two new high-resolution digital LiDAR sensors: the ultra-wide field of view OS0-128; and the long-range OS2-128. Both sensors were on display at CES 2020 and are currently being shipped to customers.
