Claim One:
1. A phase-based time-of-flight (TOF) system including a primary output source adapted to emit first energy S out having a modulation frequency ω and a phase φ, and a time of flight sensor which detects S in , which is at least a fraction of emitted said first energy that is reflected-back by a target object a distance Z away, and is adapted to determine said distance Z from a shift in said phase φ in S in , said TOF system further including: at least one auxiliary emitting unit adapted to output second energy (S out 210 - 1 ) at a frequency and phase derived from S in , the auxiliary emitting unit comprising at least one of a wireless emitting unit, and a plug-wired optical emitting unit; wherein said first energy and second optical energy are adapted to be received by said time of flight sensor in replicated modulation frequency and phase as optical energy S out emitted by said TOF system when reflected by said target object.
