Laser industry's cheaper lidar sensor coming soon

Release time: 2019.07.12 News source: Laser cutting machine | Laser marking machine | Laser engraving machine | Fiber laser marking machine | Laser equipment manufacturer-Dongguan Heli Laser Equipment Co., Ltd. Browse times:
Current lidar systems have an average of 150 integrated circuits, so these sensors are still too expensive for vehicles. According to foreign media reports, ADI (American Analog Devices Corporation) and First Sensor AG announced a cooperation to jointly develop a cheaper lidar sensor.

ADI and First Sensor are developing products that reduce the lidar signal chain, improve system performance, and enable manufacturers to reduce size, weight, power, and cost when designing sensing and sensing technologies for autonomous driving safety systems. The two companies also plan to develop other lidar products for automotive and industrial manufacturing applications. The two companies plan to use First Sensor's APDs (avalanche photodiodes) to optimize ADI's TIAs (transimpedance amplifiers). Stewart Sellars, general manager of ADI LiDAR, said that the two companies hope to provide more powerful and efficient lidar solutions and to bring lidar systems into the automated transportation market on a large-scale and commercial basis.

Laser cutting machine | Laser marking machine | Laser engraving machine | Fiber laser marking machine | Laser equipment manufacturer-Dongguan Heli Laser Equipment Co., Ltd., ADI has a long tradition in developing transportation safety sensor technology. The latest developments, including multi-channel TIAs, are designed to convert large dynamic range photocurrents into low impedance voltage signals. First Sensor also has more than 25 years of experience in manufacturing lidar APDs. Lidar APDs are a highly sensitive detector array that can convert light into photocurrent. Because the interconnection between APDs and TIAs affects the noise floor and bandwidth, it is important to optimize the interconnection between the two. By improving these two parameters, the lidar system can detect targets at a longer distance and have higher accuracy.

Dirk Rothweiler, CEO of First Sensor, said, "The market for lidar systems is maturing, and customers are looking for economically and technologically compatible solutions. It is logical to adapt APDs and TIAs to each other in the future. We can provide our customers with better lidar receiver performance. "

First Sensor and ADI will each provide a common evaluation board that system manufacturers can use to evaluate the combined solution. The cooperation with First Sensor marks the next phase of the implementation of the ADI Drive360 autonomous driving solution strategy. The ADI Drive360 technology suite makes full use of ADI's core competitiveness in high-performance MEMS, RF / mmWave, and optoelectronics / optical technologies to provide the automotive industry with a complete solution to meet the needs of high automation and autonomous driving technologies.
