Patent abstract
A method for determining whether a distance that a CW-TOF range camera provides for a scene is degraded by multipath interference (MPI) comprising operating the camera to determine a propagation phase delay and a phase delay coefficient for each of a plurality of modulation frequencies of light that illuminates the scene and using the phase delay coefficient and/or the phase delay to determine whether a distance provided by the camera is compromised by MPI.
