The temperature sensitivities of absorption and reduced scattering coefficients in the range 700-1000 nm are determined for the liquid phantom Intralipid using spatially resolved continuous wave measurements. The measurements were conducted on a 10 L heated volume of 1% Intralipid subjected to a 40-30 degrees C cooling regime. The temperature sensitivities of the absorbance coefficients are similar to that expected for pure water. However, the reduced scattering coefficients are more sensitive than can be explained by temperature related density changes, and show an unexpected relationship with wavelength. We have also found that temperature perturbations provide a useful means to evaluate instrument model performance.
利用空间分辨连续波测量法，测定了脂质乳剂液体模型在700 - 1000 nm范围内吸收系数和约化散射系数的温度敏感性。测量是在10 L加热的1%脂质乳剂中进行的，该乳剂经历了40 - 30摄氏度的冷却过程。吸收系数的温度敏感性与纯水预期的相似。然而，约化散射系数比与温度相关的密度变化所能解释的更为敏感，并且与波长呈现出意想不到的关系。我们还发现，温度扰动为评估仪器模型性能提供了一种有用的方法。
