首次提出了一種利用穆勒偏光法計算異向性渾濁介質（散射效應）平均吸收度的新方法。穆勒偏光法由偏振片和兩個電壓液晶調變器組成，為的是在計算實驗中一種異向性渾濁介質的平均吸收度。用脂肪乳劑稀釋的墨水溶液用作測試樣本。實驗結果表明，2%脂肪乳劑的墨水溶液平均吸收度隨著墨水濃度的變化而呈線性增加，分離演算法計算的其他異向光學參數也呈現合理的結果。因此，在 2mm 寬度內的脂肪乳劑混和墨水溶液測試中所得出 0.132（平均吸收/墨水濃度）的斜率。平均吸收度的平均相對標準差為 0.88%。另外，利用 LighTools 模擬並用穆勒矩陣偏光法新方法也成功地計算出平均吸收度參數。

A new methodology to extract the mean absorbance of an anisotropic turbid media (scattering effect) by using a Mueller matrix polarimetry is first proposed. A Mueller matrix polarimetry consisting of a polarizer and two liquid-crystal modulators is designed for extracting the mean absorbance of an anisotropic turbid media in experiments. The ink solution diluted with lipoplus is used as the sample for testing. The experimental results show that the mean absorbance of ink solution with 2% lipoplus increases linearly with changes of the ink concentration, and the other anisotropic optical parameters extracted by decoupling algorithm are also in good agreements. As a result, the slope of 0.132 (mean absorbance/ink concentration) is found in a solution of ink solution with 2% lipoplus within 2 mm width of a cuvette. The corresponding average standard deviation of the mean absorbance is 0.77%. Alternatively, the simulation of a Mueller matrix polarimetry by using LighTools to extract the mean absorbance based upon a new methodology is also successfully demonstrated.
