Problem Addressed

Current time-of-flight camera technologies used to calculate distance and object depth by way of shuttered CMOS sensors make use of a technique called delayed phase sampling. This method makes use of a modulated light source to illuminate the desired scene and extracts the shifts in phase from the returning optical signals to calculate distance. While this method has been used successfully in the past, it suffers from three technologically based issues that impede its usefulness, phase-wrapping, multi-path interference, and inaccuracies when signal-to-noise ratio is low.
