An expert comparison to help you choose the right equipment for your project.

Feature Time-of-Flight Phase Shift
Method Pulse timing Phase measurement
Range Very long (1km+) Medium (300m)
Speed Moderate Very fast
Accuracy Good Excellent
Service Pricing $50,000-$200,000 $40,000-$150,000
Option A Pulse-Based LiDAR

Time-of-Flight

Pulse-based ranging for long-distance outdoor scanning

Time-of-Flight LiDAR measures distance by timing laser pulse returns, offering very long range for outdoor and topographic applications.

Pros

  • Very long range
  • Sunlight resistant
  • Multi-return capable
  • Proven technology

Cons

  • Slower speed
  • Lower point rate
  • Less precise at short range
  • Larger hardware

Best For
