摘要

对人类头发光谱研究的兴趣日益增加，提出了测量其光谱准确性的问题，并要求优化实验设施。提出了一种原始的方法，获得横向头发切片，而不使用切片机和化学影响。对不同取向的人发共聚焦拉曼显微光谱测量结果进行了比较。结果表明，在从毛发外围到毛发中心的不同距离处测量的光谱除了预期的变化外，在垂直和平行于毛发轴的情况下测量的光谱也有很大的不同。

Influence of the measurement configuration on the results of Raman microspectroscopy of human hair

Increasing interest in spectroscopic studies of human hair raises the question about the accuracy of measurement of their spectra and requires optimisation of experimental facilities. An original method of obtaining transverse hair sections without using a microtome and chemical influence is proposed. The results obtained by confocal Raman microspectroscopy of human hair differently oriented with respect to the optical axis of the measuring setup are compared. It is shown that, in addition to expected changes in the spectra measured at different distances from the hair periphery in the direction to its centre, the spectra measured in the case of hair excitation perpendicular and parallel to its axis are also considerably different.
