    Abstract: Systems and methods that facilitate analysis of superficial tissue based at least in part on a depth-selective fiber optic probe are discussed herein. The depth-selective fiber optic probe can include an illumination fiber for providing light to the superficial tissue, a collection fiber for collected reflected light, a ball lens that couples the fibers, and a protective overtube that houses the ball lens and fibers. The distances between the ball lens and fibers and between the fibers can be optimized based on several factors, such as by minimizing the illumination spot size, maximizing the overlap between the illumination and collection spots, and based on the angle between the illumination and collection beams.

More specifically, the present invention is related to methods and apparatus for utilizing optical sources, systems or receivers capable of providing (source), processing (system) or recording (receiver) a multiplicity of channels of spectral information for optical coherence tomographic imaging of turbid materials. In these methods and apparatus the multiplicity of channels of spectral information that can be provided by the source, processed by the system, or recorded by the receiver are used to convey simultaneously spatial, spectral or polarimetric information relating to the turbid material being imaged tomographically. The multichannel optical coherence tomographic methods can be incorporated into an endoscopic probe for imaging a patient. The endoscope comprises an optical fiber array and can comprise a plurality of optical fibers adapted to be disposed in the patient. The optical fiber array transmits the light from the light source into the patient, and transmits the light reflected by the patient out of the patient.
