Remote FTIR reflectometry for clinical diagnostic using hollow optical-fiber probe

摘要

Infrared remote spectroscopy systems based on hollow optical-fiber probes are proposed and experimental results are shown. A hollow fiber probe with silver inner coating is used to deliver incoherent light to a target and a separate, another hollow fiber is used to collect reflected light. By using the probe, reflectance spectra of a tooth, skin, etc were successfully measured even for surfaces giving reflectance lower than 0.5%. This remote FT-IR spectroscopy is useful for endoscopic measurement of infrared reflectometry of inside body because of high flexibility and durability, non-toxicity, and low transmission losses of the hollow-fiber-based probes.
