An endoscopic probe can be provided for spectrally encoding a sample. The exemplary probe can include a lens element (32) configured to provide there through electro-magnetic radiation, and a dispersive arrangement (34, 36, 38) configured to receive at least one portion of the electro-magnetic radiation and forward a dispersed radiation to at least one section of the sample (30) from which information is being obtained. The probe can also include means for scanning an image formed by the lens element (32) of the at least one section of the sample (30). The electro-magnetic radiation can be provided by a wavelength tunable light source emitting a monochromatic radiation whose wavelength is scanned with time.
