Measuring Distance with Light in the Automotive Industry: LiDAR, Radar, and Cameras
Whether it is a safety feature or a fully autonomous vehicle, information about the distance to other vehicles on the road, unexpected road obstacles, or permanent structures near the road is of paramount importance. This webinar discusses methods of measuring distance with light (emphasizing Time of Flight LiDAR) that either are or have the potential to be employed by the industry.
Whether it is a safety feature or a fully autonomous vehicle, information about the distance to other vehicles on the road, unexpected road obstacles, or permanent structures near the road is of paramount importance. This webinar discusses methods of measuring distance with light (emphasizing Time of Flight LiDAR) that either are or have the potential to be employed by the industry.
This presentation focuses on technical aspects of :
Time of flight (ToF) light detection and ranging (LiDAR) and radar
- Physics concept
- Why we need LiDAR
- Design challenges: Wavelength, light source, photodetector detector, and beam steering
- Types of ToF LiDAR: Mechanical, flash, optical phase array, and more
Frequency modulated continuous wave (FMCW) radar
- Physics concept
- Comparison with ToF radar
FMCW LiDAR
- Optical mixing
- Amplitude chirp-modulation with electrical mixing
- Phase comparison LiDAR
Stereovision: Active and passive triangulation

Slawomir S. Piatek
Professor of Physics at NJIT & Hamamatsu Corporation consultant
Hamamatsu Corporation
Slawomir S. Piatek has been measuring proper motions of nearby galaxies using images obtained with the Hubble Space Telescope as a senior university lecturer of physics at New Jersey Institute of Technology. He has developed a photonics training program for engineers at Hamamatsu Corporation in New Jersey in the role of a science consultant. Also at Hamamatsu, he is involved in popularizing a SiPM as a novel photodetector by writing and lecturing about it, and by experimenting with the device. He earned a Ph.D. in Physics at Rutgers, the State University of New Jersey.
