fasevisninger
Fasevisninger, often translated as phase unwrapping, is a crucial process in many fields that analyze periodic phenomena, particularly in signal processing and imaging. It deals with the ambiguity inherent in phase measurements, where the phase angle of a signal is only known modulo 2π. This means that if a signal has a phase of 3π/2, it is indistinguishable from 7π/2 or -π/2 based solely on the raw measurement.
The goal of fasevisninger is to reconstruct the true, continuous phase by adding or subtracting multiples of
Common methods for fasevisninger include path following algorithms, where the unwrapping proceeds along a connected path
