摘要：

An innovative spectroscopic diagnostic method has been developed for investigation of different regions of normal human skin tissue. This new method is a combination of Fourier transform infrared fiberoptic evanescent wave (FTIR-FEW) spectroscopy and fiber optic techniques for the middle infrared (MIR) wavelength range (3 to 20 mu m) The fiber optical sensors we have used are characterized by low optical losses and high flexibility for remote analysis. Our fiber optical accessories and method allows for direct interaction of the skin tissue with the fiber probe and can be utilized with a diversity of standard commercial Fourier transform spectrometers. The FTIR-FEW technique, using nontoxic unclad fibers in the attenuated total reflection(ATR) regime, is suitable for noninvasive, fast, sensitive investigations of normal skin in vivo for various medical diagnostics applications including studies of acupuncture points. Here we present the first data on infrared spectra of skin tissue in vivo for normal skin and several acupuncture points in the range of 1300 to 1800 cm(-1) and 2600 to 4000 cm(-1).
