1. A method for optical coherence tomography (OCT), the method comprising:
performing a plurality of measurement sessions; wherein different measurement sessions are associated with different optical paths lengths of a reference arm of an interferometer;
wherein a measurement session that is associated with a given optical path length of the different optical paths lengths comprises:
performing measurement iterations, wherein each measurement iteration comprises:
illuminating a sample by radiation that passes through a sensing arm of the interferometer;
phase modulating of the radiation that propagates within an arm of the interferometer, wherein the arm is selected out of the sensing arm and a reference arm, wherein the phase modulation has a modulation cycle;
merging radiation that exits the reference arm with radiation from the sensing arm that returned from a sub-region of a sample to provide an interference pattern;
generating signals indicative of the interference pattern by two dimensional (2D) arrays of sensing related elements of a sensing unit, wherein different 2D arrays of sensing related elements sample the interference pattern at different detection periods within the measurement iteration; wherein a duration of each one of the detection periods is a fraction of the modulation cycle; and
aggregating, by the sensing unit, signals obtained by each one of the sensing related elements during the measurement iterations to provide measurement session results.
