Abstract
Time-of-flight (TOF) phase-derived data is dealiased by operating the TOF system using at least two close-together modulation frequencies fand fthat are close to the TOF system maximum modulation frequency f. On one hand, phase data acquired by the TOF is associated with a desirably long aliasing interval range Znormally associated with a rather low modulation frequency. On the other hand, phase data acquired by the TOF system is also associated with the high precision certainty as to Z value normally associated with high modulation frequency. Preferably the TOF system operates always close to fsuch that TOF operating efficiency is high, and system signal/noise ratio is not substantially degraded using the present invention.
