Abstract: Method and apparatus according to an exemplary embodiment of the present invention can be provided. For example, first data associated with a first signal received from at least one region of at least one sample can be provided based on a first modality, and second data associated with a second signal received from the at least one sample can be provided based on a second modality which is different from the first modality. Third data associated with a reference can be received. Further data can be generated based on the first, second and third data. In addition, third data associated with a second signal received from the at least one sample can be obtained. Each of the third data can be based on a further modality which is different from the first modality and the second modality, and the further data can be further determined based on the third data. Further, the first modality can be a spectral-encoded modality, and the second modality can be a non-spectral-encoding modality.

Abstract: An apparatus for applying a plurality of electromagnetic radiations to a sample is provided. In one exemplary embodiment, the apparatus can include an arrangement which has a specific portion with a plurality of channels. One of channels can facilitate a first radiation of the radiations to be forwarded to the sample that is within an anatomical structure, and another one of the channels can facilitate a second radiation of the radiations to be forwarded to the sample. The first radiation may have a first wavelength band, and the second radiation may have a second wavelength band. The first wavelength band may be substantially different from the second wavelength band. According to another exemplary embodiment, the first radiation can be adapted to be delivered to a first area of the sample, and the second radiation may be capable of being delivered to a second area of the sample. The first area may be substantially enclosed by the second area.

Abstract: In one exemplary embodiment of the present invention, method and system can be provided for obtaining information associated with at least one portion of a sample. For example, a temperature change can be caused in the portion of the sample. At least one first electro-magnetic radiation can be forwarded to a section near or in the portion of the sample. A deformation of the section can be identified at a plurality of depths as a function of (i) a phase of at least one second electro-magnetic radiation provided from the section, and/or (ii) a rate of change of the phase and/or an amplitude of the second electro-magnetic radiation. In another exemplary embodiment of the present invention, method and system can be provided for controlling a temperature distribution in a sample. For example, an electro-magnetic radiation can be provided to the section in the sample at a particular wavelength.

Abstract: Method, apparatus and arrangement according an exemplary embodiment of the present invention can be provided for analyzing and/or illustrating at least one portion of an anatomical structure. For example, light can be forwarded to such portion so as to generate first information which is related to the portion. For example, the light can be provided on or within a subject. The first information can be received, and at least one section of the portion may be selected based on the first information so as to generate second information. A magnification of a display of the portion may be progressively modified as a function of the second information.

Abstract: Exemplary systems and methods for obtaining a photoluminescence radiation from at least one portion of a sample can be provided. For example, using the exemplary embodiment, it is possible to receive a first radiation and disperse the first radiation into at least one second radiation and at least one third radiation. The second and third radiations can be provided to different locations of the portion. In addition, it is possible to receive the photoluminescence radiation from the portion based on the second and third radiations.

Abstract: Apparatus, method and storage medium which can provide at least one first electro-magnetic radiation to a sample and at least one second electromagnetic radiation to a reference, such that the first and/or second electromagnetic radiations have a spectrum which changes over time. In addition, a first polarization component of at least one third radiation associated with the first radiation can be combined with a second polarization component of at least one fourth radiation associated with the second radiation with one another. The first and second polarizations may be specifically controlled to be at least approximately orthogonal to one another.

Abstract: Apparatus, system and method are provided which utilize signals received from a reference and a sample. In particular, a radiation is provided which includes at least one first electromagnetic radiation directed to the sample and at least one second electromagnetic radiation directed to the reference. A frequency of the radiation varies over time. An interference can be detected between at least one third radiation associated with the first radiation and at least one fourth radiation associated with the second radiation. It is possible to obtain a particular signal associated with at least one phase of at least one frequency component of the interference, and compare the particular signal to at least one particular information. Further, it is possible to receive at least one portion of the radiation and provide a further radiation, such that the particular signal can be calibrated based on the further signal.

Abstract: An optical apparatus includes an optical fiber. A plurality of individual optical fiber deformation structures are positioned adjacent along a length of the optical fiber. Each of an individual optical fiber deformation structure introduces a mechanical or index deformation of a portion of the optical fiber to create perturbation in the optical modes in the fiber and provide a coherent coupling between two modes in the optical fiber.

Abstract: A folded Sagnac fiber optic acoustic sensor array operates in a manner similar to a Sagnac interferometer but uses a common delay path to reduce distributed pickup in downlead fibers. The fiber optic acoustic sensor array is used to detect acoustic waves in water. By basing the folded Sagnac sensor array on operating principles similar to the Sagnac interferometer rather than basing the array on a Mach-Zehnder interferometer, the sensor array has a stable bias point, has reduced phase noise, and allows a broadband signal source to be used rather than requiring a more expensive narrowline laser. A large number of acoustic sensors can be multiplexed into the architecture of the folded Sagnac fiber optic acoustic array.
