Abstract:
1. An apparatus for applying a plurality of electro-magnetic radiations to a sample, comprising: an interferometric system; a catheter arrangement having a specific portion with a plurality of waveguides, and provided in communication with the interferometric system, wherein a first one of the waveguides facilitates a first radiation of the radiations to be forwarded to the sample that is within an anatomical structure, and a second one of the waveguides facilitates a second radiation of the radiations to be forwarded to the sample, the first radiation having a first wavelength band, and the second radiation having a second wavelength band, wherein the first wavelength band is different from the second wavelength band, wherein the interferometric system includes a computer arrangement that is configured to determine information associated with an effect induced by one of the first radiation or the second radiation on the sample, and wherein a third one of the waveguides transmits the first and second radiations, and wherein the first and second radiations transmitted via the third one of the waveguides are separated within the catheter arrangement, and provided into the first and second ones of the waveguides, respectively; and a rotary coupler arrangement which receives the radiations via at least one fiber and provides the first radiation to the waveguides, wherein, when activated, the rotary coupler arrangement causes the specific portion to be continuously rotated within the anatomical structure.
