Abstract

Apparatus and method can be provided, whereas a particular radiation which includes at least one first electro-magnetic radiation can be directed to at least one sample and at least one second electro-magnetic radiation can be directed to a reference. The first electro-magnetic radiation having a particular cross-sectional width may be applied to at least one portion of the sample to generate at least one third electro-magnetic radiation. The first electro-magnetic radiation can be provided in the portion along a particular axis for a distance between a multiplier of 0.5 and 100 of the particular cross-sectional width. An interference can be detected between the third electro-magnetic radiation associated with the first electro-magnetic radiation and at least one fourth electro-magnetic radiation associated with the second electro-magnetic radiation. Further, an asymmetrical cross-sectional area of the first electro-magnetic radiation can be provided.
