1. An apparatus comprising:

  • at least one hardware first arrangement including a source which provides a radiation which includes at least one first electro-magnetic radiation directed to a sample and at least one second electro-magnetic radiation directed to a reference, wherein a frequency of the radiation provided by the at least one first arrangement varies over time; and

    at least one hardware second arrangement which includes a detector that detects a particular interference signal between at least one third radiation associated with the at least one first radiation and at least one fourth radiation associated with the at least one second radiation,wherein that particular interference signal is detected by the detector across a first radiation frequency range,wherein the at least one second arrangement obtains at least one first phase of at least one frequency component of the particular interference signal, and wherein the at least one second arrangement includes a hardware computing arrangement which compares the at least one first phase with at least one second phase of at least one frequency component of a previously-detected interference signal which is detected by the detector across a second radiation frequency range, andwherein the hardware computing arrangement generates at least one image of at least one portion of the sample that substantially excludes information caused by a difference between the first and second radiation frequency ranges based on the comparison and as function of the interference signals.
