We report experimental evidence of correlation-induced spectral changes in biological tissues. The overall spectral shift in our transmission measurements is to the red and the mean wavelength of the original spectrum is up 10% larger. These results indicate that the spectral changes due to elastic scattering are significant and likely to hinder all spectroscopic measurements based on the inelastic (i.e., emission and absorption) interaction between light and tissues. Thus, simultaneous morphology and spectral measurements are required for accurate measurements spectroscopic information.
我们报告了生物组织中相关诱导光谱变化的实验证据。在我们的传输测量中，整体光谱偏移到红色，原始光谱的平均波长增加了 10%。这些结果表明，由于弹性散射引起的光谱变化是显著的，可能会阻碍所有基于光与组织之间的非弹性（即发射和吸收）相互作用的光谱测量。因此，需要同时进行形态和光谱测量，以获得准确的光谱信息。
