1. An apparatus for obtaining information associated with an anatomical structure, comprising:

  • a housing;

    at least one lens that is different from the housing, and which is configured to provide there through electro-magnetic radiation, wherein the electro-magnetic radiation is provided by at least one of a broadband source or a wavelength tuned source;

    an optical waveguide configured to transmit the electro-magnetic radiation from the structure;

    at least one further arrangement including a computer which is structured to obtain the information based on the electro-magnetic radiation obtained from the structure, wherein the information is at least one of a two-dimensional image or a three dimensional image; and

    a dispersive arrangement including a grating which is configured to receive at least one portion of the electro-magnetic radiation and forward a dispersed radiation thereof to at least one section of the structure regarding which the information is being obtained, wherein the grating has a groove density that is at least 1200 lines/mm, wherein the lens and the dispersive arrangement are provided within at least one portion of the housing and in an optical path between the optical waveguide and a location of the apparatus at which the electro-magnetic radiation is received from the anatomical structure, and wherein the at least one portion of the housing has a diameter of at most 1 mm.
