Time-of-flight (ToF) range imaging is an established full-field depth acquisition technology. ToF is prone to several forms of error, notably multi-path interference (MPI). Frequency stepping ToF mitigates these errors, but efficient computational methods suffer from bandwidth limitations. We introduce a new acquisition method based on simultaneous phase and frequency stepping, which is capable of running in real time and reduces error compared to phase stepping and frequency stepping alone.
