Multi-fiber optical probe and optical coherence tomography system
Multichannel optical coherence systems and methods involving optical coherence tomography (OCT) subsystems are operably and respectively connected to optical fibers of a multichannel optical probe, such that each optical fiber forms at least a distal portion of a sample beam path of a respective OCT subsystem. The optical fibers are in optical communication with distal optical elements such that external beam paths associated therewith are directed towards a common spatial region external to the housing. Image processing computer hardware is employed to process OCT signals obtained from the plurality of OCT subsystems to generate an OCT image dataset comprising a plurality of OCT A-scans and process the OCT image dataset to generate volumetric image data based on known positions and orientations of the external beam paths associated with the OCT subsystems.

Systems, devices, methods, apparatus and computer-accessible media for providing optical imaging of structures and compositions
Exemplary systems, devices, methods, apparatus and computer-accessible media for providing and/or utilizing optical frequency domain imaging (OFDI) and fluorescence of structures and, e.g., multimodality imaging using OFDI techniques and fluorescence imaging techniques are described. For example, an arrangement can provide at least one electro-magnetic radiation to an anatomical structure. Such exemplary arrangement can include at least one optical core and at least one cladding at least partially surrounding the fiber(s). A region between the optical core(s) and the cladding(s) can have an index that is different from indexes of the optical core(s) and the cladding(s). The arrangement can also include at least one apparatus which is configured to transmit the radiation(s) via the optical core(s) and the cladding(s) to the anatomical structure.
COMMON PATH WAVEGUIDES FOR STABLE OPTICAL COHERENCE TOMOGRAPHY IMAGING
An OCT imaging system may include an OCT light source operable to emit an OCT light beam, and a beam splitter operable to split the OCT light beam into a sample beam, transferred to a sample arm waveguide, and a reference beam, transferred to a reference arm waveguide. The sample arm waveguide and the reference arm waveguide may be coupled together within a cladding, wherein the cladding improves a calibration of a generated OCT image by fixing axial movement of the sample arm and reference arm waveguides relative to one another. By routing long reference and sample arm waveguide fibers together in the OCT system using a sheath/cladding, OCT image offset due to asymmetrical fiber stretching can be minimized or eliminated.

An optical probe 40 used for the vascular optical tomographic imaging apparatus 100 includes an optical fiber 10 having a central axis 14 and a translucent lens member 20 fixed to a tip surface 12 of the optical fiber. The lens member has an outer circumferential surface surrounding an extension axis 22 obtained by extending the central axis 14 of the optical fiber forward, a rear end surface 26 intersecting the extension axis, and a tip surface 28 intersecting the extension axis. The tip surface of the lens member is a surface extending obliquely with respect to the extension axis. The outer circumferential surface of the lens member has, at least in part, a cylindrical surface portion 24 around the extension axis or a cylindrical surface portion about an axis parallel to the extension axis. The optical probe is configured so that light emitted from the tip of the optical fiber is incident on the tip surface along the extension axis, and light reflected by the tip surface is emitted from the lens member through the cylindrical surface portion.
