Abstract

According to an exemplary embodiment, systems and methods can be provided for compensating for, reducing and/or eliminating data associated with at least one aberration provided within a sample. For example, using such exemplary systems and methods, it may be possible to transmit at least one first electromagnetic radiation to the sample via an optical fiber. At least one second electromagnetic radiation can be received from the sample, and the first and second radiations may be associated with one another At least one first intensity of at least one portion of the second radiation within a core of the optical fiber and at least one portion of at least one second intensity of the second radiation within a cladding of the optical fiber at least partially surrounding to the core can be detected. Further, the first radiation and/or the second radiation can be modified as a function of the first and second intensities so as to compensate for, reduce and/or eliminate the data associated with the aberration.
