Physics principles, design challenges, and new developments

The idea of a self-driving car permeates our popular culture, creating an expectation that it soon will become an everyday reality. The automotive industry and academia are actively engaged in applied research developing systems needed to make cars fully autonomous. One such system is LiDAR: it is needed to provide high-definition 3D information of the car’s surroundings at the video rate and up to a distance of about 200 meters. A complete design of a functional LiDAR is proving to be elusive, with beam steering and photodetection presenting the greatest engineering challenge. This is a third webinar sponsored by Hamamatsu that explores technical aspects of automotive LiDAR. Its focus is a Solid State LiDAR - a specific design that does not contain any moving parts – with the following topics:

  • Review of time-of-flight (ToF) and frequency modulation continuous wave (FMCW) LiDAR concepts
  • Discussion of beam steering concepts
  • Discussion of challenges of today’s LiDAR systems
  • Discussion of future solid state LiDAR concepts
