Exemplary arrangement, apparatus, method and computer accessible can be provided. For example, using the exemplary arrangement, apparatus and method, it is possible to configured to propagate at least one electro-magnetic radiation. Indeed, it is possible to receive, using at least one first arrangement, a first portion of the at least one electro-magnetic radiation directed to a sample and a second portion of the least one electro-magnetic radiation directed to a reference, the first arrangement can be structured to at least partially reflect and at least partially allow to transmit the first and second portions. In addition, it is possible to receive, using a second arrangement, (i) a third portion of the electro-magnetic radiation associated with at least one of the transmitted first portion or the reflected first portion from the sample and (ii) a fourth portion of the electro-magnetic radiation associated with at least one of the second transmitted portion of the least one electro-magnetic radiation or the reflected second portion from the reference. The third and fourth portions can travel at least partially along substantially the same path toward the second arrangement, Further, the second arrangement can be configured to receive the reflected first and second portion(s) which interfere with one another, and generate at least one signal which includes information associated with at least one fluctuation in an uncommon path of the first and second portions prior to a receipt thereof by the at least one first arrangement. In addition or alternatively, the second arrangement can be configured to determine information regarding a spectrally resolved interference associated with the third and fourth portions.
