Spectrally-encoded endoscopy techniques, apparatus and methods

An apparatus for obtaining information for a structure, comprising:

• at least one first optical fiber arrangement configured to transceive at least one first electro-magnetic radiation, and including at least one fiber;
• at least one dispersive second arrangement configured to receive a particular radiation which is at least one of the at least one first electro-magnetic radiation, and forward a spectrally-dispersed radiation thereof to at least one section of the structure;
• at least one focusing third arrangement in optical communication with the at least one first optical fiber arrangement,
• wherein the at least one focusing third arrangement is configured to focus and provide there through the spectrally-dispersive radiation to generate the focused electro-magnetic radiation,
• wherein at least one end of the at least one fiber is connected to at least one of the at least one focusing third arrangement or the at least one dispersive second arrangement, and
• wherein at least two of the first, second and third arrangements are provided in a monolithic configuration.
