Osram Presents New Infrared Laser for Short-Range LiDAR Applications

How long do you think cars will be steered by a driver? For autonomous driving to become widespread, several legal and technological hurdles will have to be overcome in the upcoming years. Nevertheless, car manufacturers and mobility service providers are already working on their visions for driverless vehicles. The need for autonomous vehicles to more comprehensively and reliably detect their surroundings makes the number and arrangement of sensors, such as Light Detection And Ranging (LiDAR), more critical. As the market leader for LiDAR lasers, Osram Opto Semiconductors plays a central role in the realization of these applications. With the SPL DP90_3, the semiconductor expert is expanding its portfolio with a component that has been specially developed for high-resolution, near-field detection in LiDAR systems.

There is now a broad consensus that only a sensor fusion of LiDAR, radar and camera systems can provide the necessary security for fully autonomous driving. Each of these technologies has advantages and disadvantages depending on the respective scenario, but overall, the better they are coordinated, the safer the vehicle moves through traffic. For example, LiDAR systems are strong in generating high-resolution 3D information in real time.

Long-range LiDAR is used to detect objects up to approximately 250 meters away. The immediate surroundings of the car must also be reliably captured by short- or mid-range LiDAR, which covers a distance up to approximately 90 meters from the vehicle. Short- or mid-range LiDAR covers classic traffic situations such as passing cars on highways or driving in urban traffic.

With SPL DP90_3, Osram is presenting a new single-channel pulsed laser that features improved beam quality and particularly compact dimensions. Thanks to its space-saving footprint of just 0.3 mm x 0.6 mm, system manufacturers can create extremely compact designs. An efficiency of around 30 percent helps reduce the overall cost of the system during operation. With an optical output of 65 Watts at 20 A, the component not only has an absolute unique selling point but is also ideally suited for capturing the immediate vehicle surroundings, ensuring high-resolution images for subsequent systems.

"Which components will be used in which systems for autonomous driving is going to be an important development as we get closer to making autonomous vehicles accessible for all," explains Karl Leahy, Director of Product Marketing at Osram Opto Semiconductors. "As automotive manufacturers make these decisions, our customers already know that they can trust our solutions because of our long history of experience in the development and production of special infrared lasers for LiDAR systems, and the new SPL DP90_3 is a great example of our expertise."

Osram will be demonstrating the SPL DP90_3 in the Vixar booth #4568 at the SPIE Photonics West 2020 at The Moscone Center in San Francisco, February 4-6.
