Today’s reality Q: Can you buy FMCW components or a complete system today? A: Absolutely. There are many companies offering one or both paths to a complete system. For example, the Aeva CoreVision Lidar-on-Chip Technology of Figure 1 with a 500-meter range has an integrated silicon photonics module. The module incorporates all key FMCW LiDAR […]

FAQ on the basics of FMCW LiDAR: part 3
This alternative to time-of-flight LiDAR has unique complexities and distinct attributes. Modeling and simulation Q: What design analysis is done on an FMCW LiDAR system? A: In a word: lots. Much of the analysis parallels or leverages what has been done for radar, as there are so many similarities in operating principles and the analytical […]
FAQ on the basics of FMCW LiDAR: part 2
This alternative to time-of-flight LiDAR has unique complexities and distinct attributes. Part one begins our look at what FMCW LiDAR is, the architecture and components it uses, and its performance capabilities. Electronic and optical components build a system Q: What hardware components are needed to create a basic FMCW LiDAR system? A: One perspective is […]
FAQ on the basics of FMCW LiDAR: part 1
This alternative to time-of-flight LiDAR has unique complexities and distinct attributes. When engineers hear the phrase LiDAR, an acronym for Light Detection and Ranging, they generally think of time-of-flight (ToF) systems. ToF LiDAR is widely used in automotive and robotic applications to “see” surroundings and obstacles. But there is another, radically different LiDAR approach: frequency […]
What are the latest advances in radar and LiDAR technologies for sensor fusion: part 3
In addition to improved performance from individual sensing technologies, including radar and light detection and ranging (LiDAR), other ongoing advances for sensor fusion are required for more complex advanced driver-assistance systems (ADAS) and to achieve the highest levels of autonomous driving (AD). Future trends in other technologies for sensor fusion Ongoing advances to improve sensor […]
What are the latest advances in radar and LiDAR technologies for sensor fusion: part 2
In contrast to the widespread use of radar sensing, automotive applications for light detection and ranging (LiDAR) sensors are much more limited. This is due in part to their bulky size (especially electromechanical LiDAR) and high cost. Similar to radar designs, except that LiDAR uses lasers instead of radio waves for detection and ranging, it […]
What are the key considerations for integrating lidar and radar data for robust perception: part 2
Practical techniques for improving sensor fusion accuracy In addition to the usual design techniques for improving sensor performance such as (1) calibration to correct errors including multi-point calibration for higher accuracy, and regular recalibration to correct for drift over time; (2) signal conditioning to correct for errors like offset and linearity, amplified signals for improved signal-to-noise […]
How does fusion timing impact sensors?
Today with LiDAR included as one of the potential sensing technologies, low-level fusion still seems to be a popular design approach.
How will LiDAR sensing be used in industrial applications?
Light Detection and Ranging or LiDAR is often used in the latest searches for ancient ruins (lost cities and walls), underwater exploration, and even treasure hunting to display 3D imaging that other techniques cannot provide. LiDAR is also one of the key technologies (besides radar and cameras) that is integrally involved in the quest for […]
How will sensing become part of 6G cellular?
As many people worldwide are still getting used to, benefiting from the improvements, and confronting the shortcomings of 5G cellular, standards organizations and industry cooperatives are busy preparing for 6G. This next-generation communications network will add sensing to its capabilities. Called integrated sensing and communication (ISAC) or joint communications and sensing (JCAS), the addition of […]
