Apparatus and method according to an exemplary embodiment of the present invention can be provided for analyzing tissue. For example, the apparatus can include at least one first arrangement configured to illuminate at least one anatomical structure with at least one of at least one electro-magnetic radiation. The apparatus can also include at least one second arrangement that may include at least two wave-guiding arrangements associated with one another that are configured to receive a further electro-magnetic radiation reflected from the tissue and transmit at least one speckle pattern associated with the further electro-magnetic radiation. The wave-guiding arrangements may be structured so as to reduce crosstalk therebetween.
