Single fiber reflectance spectroscopy (SFRS) is a noninvasive procedure to quantitate tissue absorption and scattering properties. It can be used to diagnose different diseases such as malignancy and pre-cancerous conditions. The measurement is done with a fiber optic probe in contact with the tissue surface. Herein, the effect of probe pressure on the extracted parameters from human lip spectra was studied. Thirty-three normal subjects were examined with three exerted pressure levels on the right, middle and left parts of their lips. The results showed variation of spectroscopic parameters with different pressure levels. However, the effect was seen between a very mild contact (pressure 1) and the other reasonably practical pressure levels normally used in the medical centers. SFRS can be used as a reliable diagnostic tool in clinics.
单纤维反射光谱法（SFRS）是一种用于定量组织吸收和散射特性的非侵入性方法。它可用于诊断不同疾病，如恶性肿瘤和癌前病变。测量是通过与组织表面接触的光纤探头进行的。在此，研究了探头压力对从人唇光谱中提取的参数的影响。33名正常受试者在其嘴唇的右侧、中部和左侧施加三种压力水平进行检查。结果表明，光谱参数随不同压力水平而变化。然而，这种影响是在非常轻微的接触（压力1）和医疗中心通常使用的其他合理实用的压力水平之间观察到的。SFRS可作为临床可靠的诊断工具。
