Abstract: A fiber-optic probe for multi-modal characterization of a tissue. The fiber optic probe may comprise a first group of fibers associated with a first modality of light. The first group of fibers may comprise a first light delivery fiber and a first light collection fiber. The fiber optic probe may also comprise a second group of fibers associated with at least a second modality of light, the second group of fibers comprising a second light delivery fiber and a second light collection fiber; The fiber optic probe may also comprise a longpass filter positioned distal to the first group of fibers and a lens positioned distal to the filter. The fiber optic probe may also comprise. The fiber optic probe may include the second group of fibers bypassing the filter. The second group of fibers may bypass the filter.

Abstract: An imaging apparatus comprises a first optical fiber configured to deliver a source beam of light generated by a light source and a polarizing beam splitter configured to polarize the source beam of light and direct diffusely reflected light toward a collection fiber optically coupled to an optical detector. The imaging apparatus also comprises a mirror configured to reflect the polarized beam of light onto the lens and direct reflected light away from a lens. The lens is configured to focus the polarized source beam of light onto an area of sample material and focus diffusely reflected light from the sample material into a reflection beam. The imaging apparatus also comprises a plano-convex curvature matching window disposed at a focal plane of the lens, wherein a convex surface of the curvature matching window is substantially matched to the focal plane curvature of the imaging lens.
