Abstract
Accordingly, exemplary embodiments of an apparatus obtaining information associated with a structure can be provided. For example, with a first arrangement, it is possible to separate at least one first electro-magnetic radiation into a first radiation and a second radiation forwarded to the structure, with the first and second radiations having different path lengths. Using a second arrangement, it is possible to receive third and fourth radiations from the structure associated with the first and second radiations and a fifth radiation received from a reference. Further, with a third arrangement, it is possible to generate data corresponding to an amount of a ranging depth within the structure associated with the second arrangement. For example, a difference between the path lengths of the first and second radiations is equal or greater than the ranging depth.
