How it works

TOF - Time-of-Flight

3D Vision Technology - Time of Flight - Zivid

Principles

  • Measure the time of emitted light and reflected response.
  • Time delay (pulse) and phase based.

Key considerations

  • Utilize time as «baseline».
  • Potentially compact with no occlusion.
  • Large measurement range (several hundred meters).
  • Very fast (real-time video rates).
  • Sensitive to reflections.
  • Limited absolute accuracy.
  • Complex manufacturing.
  • Typically sub-HD resolutions.
