Exemplary system, method and computer accessible medium are provided for determining at least one characteristic of a target object located behind or within a medium. For example, it is possible to identify a reference object that is located behind or within the medium. The target object and the reference object can be irradiated via a surface of the medium using at least one electromagnetic wave. At least one acoustic signal provided from an irradiated tissue volume that is responsive to the electromagnetic wave(s) can be measured. Calibration information can be obtained from the acoustic signal measured from the reference object based on at least one known property of the reference object. Then, the characteristic(s) of the target object can be determined based on the calibration information and the acoustic signal from the target object.
