摘要:
According to an exemplary embodiment of the present disclosure, an apparatus can be provided which can include at least one first arrangement providing a radiation, and including a splitter structure separating the radiation into at least one first electro-magnetic radiation directed to a sample and at least one second electro-magnetic radiation directed to a reference. A frequency of the radiation provided by the first arrangement can be varied over time by the first arrangement. The apparatus can also include at least one detector second arrangement configured to detect a first interference and a second interference between at least one third radiation associated with the first radiation(s) and at least one fourth radiation associated with the second radiation(s), whereas the first and second interferences can be different from one another. The second arrangement(s) can include a computer that can be further configured to (i) obtain information associated with at least one relative phase between the first and second interferences, and (ii) determine an absolute phase of the first interference and/or the second interference based on the information.
