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.
