Claim 12:
13. A non-transitory computer-readable medium storing one or more instructions that, when executed by a processor, cause the processor to:
determine a first delta phase for each of a plurality of temporal samples of a reflected waveform for a location based, at least in part, on a difference between a first quadrature pair of a plurality of first quadrature pairs associated with a first temporal sample of the plurality of temporal samples and a second quadrature pair of the plurality of first quadrature pairs associated with a second temporal sample of the plurality of temporal samples, wherein the reflected waveform is received from a sensor that reflects an optical signal;
determine a second delta phase for each of the plurality of temporal samples of the reflected waveform for the location based, at least in part, on a difference between a first quadrature pair of a plurality of second quadrature pairs associated with the first temporal sample of the plurality of temporal samples and a second quadrature pair of the plurality of second quadrature pairs associated with the second temporal sample of the plurality of temporal samples;
determine a delta phase difference for each of the plurality of temporal samples of the reflected waveform for the location based, at least in part, on a difference between the first delta phase and the second delta phase;
determine a phase jump of at least one of a first wavelength and a second wavelength based, at least in part, on the delta phase difference;
determine a first average magnitude for each of the plurality of temporal samples associated with the first wavelength;
determine a second average magnitude for each of the plurality of temporal samples associated with the second wavelength; and
determine a corrected phase measurement for the location based, at least in part, on the delta phase difference the first delta phase, the second delta phase, the first average magnitude and the second average magnitude.
