Abstract:
1. An apparatus for applying a plurality of electro-magnetic radiations to a sample, comprising: a first arrangement which is configured to provide the radiations, at least two of which are separated into a first radiation to be provided to the sample, and an additional radiation to be provided to a reference arm; a catheter second arrangement having a specific portion with a plurality of channels, wherein one of the channels facilitates the first radiation to be forwarded to the sample that is within an anatomical structure, and another one of the channels 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 channels further include a first fiber transmitting the first and second radiations, and wherein the first and second radiations transmitted via the first fiber are separated within a catheter body of the catheter second arrangement, and provided into the one of the channels having a second fiber and the other one of the channels having a third fiber, wherein the catheter body in which the separated first and second radiations are transmitted is configured to be inserted into the anatomical structure; a processor third arrangement configured to (i) receive first information associated with the first radiation reflected from the sample, and (ii) determine an effect of the second radiation on the sample based on the first information; and a rotary coupler arrangement which receives the radiations via at least one fourth fiber and provides the first radiation to the first fiber, wherein, when activated, the rotary coupler arrangement causes the specific portion to be continuously rotated within the anatomical structure.
