3 Principle description and key parameters
3.1 Ranging Principle
TF-Luna is using Time of Flight (ToF) principle to measure the distance and it periodically emits
near infrared modulated waves. TF-Luna calculates the time by measuring the phase difference
between the original wave and the reflection wave and uses that time to get relative distance, as
shown in Figure 1.
