摘要：
Exemplary embodiments of probes, apparatus, systems and methods can be provided which provide at least one electro-magnetic radiation to at least one sample. For example, a plurality of axicon lenses can be provided which are configured to provide the electro-magnetic radiation(s) having at least partially annulus shape. In addition or alternatively, at least one optical arrangement can be provided which is configured to forward at least one radiation to the sample therethrough having at least partially circularly-symmetric pattern. For example, at least one first portion of the radiation transmitted through a circular section of the pattern can have an optical path-length that is different from an optical path-length of at least one second portion of the radiation transmitted through at least one other section of the pattern.
