Photonics Could Reduce The Cost Of Lidar
By Karen Heyman - 05 Sep, 2024 - Comments: 0

Using light to move data over shorter distances is becoming more common, both because there is much more data to move around and because photons are faster and cooler than electrons. Using optical fiber for mission-critical communication is already well established. It has been the preferred PHY for long-haul communications for decades because it doesn’t suffer from the attenuation losses ... » read more

Sensor Requirements For Developing Robust Environment Perception Systems
By Ron Martin - 18 Jul, 2024 - Comments: 0

In recent years, sensor systems for environment perception have become increasingly important – whether for adaptive robotics, automated driving, industrial process and quality control, or condition monitoring. The aim is always to detect and interpret certain environmental characteristics. In doing so, it’s important to choose not only the right algorithm but also the right sensor or senso... » read more

Silicon Photonics Manufacturing Ramps Up
By Gregory Haley - 21 Mar, 2024 - Comments: 0

Circuit scaling is starting to hit a wall as the laws of physics clash with exponential increases in the volume of data, forcing chipmakers to take a much closer look at silicon photonics as a way of moving data from where it is collected to where it is processed and stored. The laws of physics are immutable. Put simply, there are limits to how fast an electron can travel through copper. The... » read more

Abstract: "Lidar, a technology at the heart of autonomous driving and robotic mobility, performs 3D imaging of a complex scene by measuring the time of flight of returning light p... » read more

Confusion Grows Over Sensor Fusion In Autos
By Ann Mutschler - 06 Jul, 2023 - Comments: 0

A key strategy for fully autonomous vehicles is the ability to fuse together inputs from multiple sensors, which is essential for making safe and secure decisions, but it's turning out to be much harder than first imagined. There are multiple problems that need to be solved, including how to partition, prioritize, and ultimately combine different types of data, and how to architect the proce... » read more

How Many Sensors For Autonomous Driving?
By John Koon - 01 Jun, 2023 - Comments: 0

With the cost of sensors ranging from $15 to $1,000, carmakers are beginning to question how many sensors are needed for vehicles to be fully autonomous at least part of the time. Those sensors are used to collect data about the surrounding environment, and they include image, lidar, radar, ultrasonic, and thermal sensors. One type of sensor is not sufficient, because each has its limitation... » read more

Designing Crash-Proof Autonomous Vehicles
By John Koon - 10 May, 2023 - Comments: 0

Autonomous vehicles keep crashing into things, even though ADAS technology promises to make driving safer because machines can think and react faster than human drivers. Humans rely on seeing and hearing to assess driving conditions. When drivers detect objects in front of the vehicle, the automatic reaction is to slam on the brakes or swerve to avoid them. Quite often drivers cannot react q... » read more
