We propose a method for estimating the stiffness of bio-specimens by measuring their linear retardance properties under applied stress. For this purpose, we employ an epi-illumination Mueller matrix microscope and show the procedures for its calibration. We provide experimental results demonstrating how to apply Mueller matrix data to elastography, using chicken liver and chicken heart as biological samples. Finally, we show how the histograms of linear retardance images can be used to distinguish between specimens and quantify the discrimination accuracy.
我们提出了一种通过测量生物样本在施加应力下的线性延迟特性来估计其刚度的方法。为此，我们使用落射照明穆勒矩阵显微镜，并展示了其校准程序。我们提供了实验结果，展示了如何将穆勒矩阵数据应用于弹性成像，使用鸡肝和鸡心作为生物样本。最后，我们展示了线性延迟图像的直方图如何用于区分样本并量化辨别准确性。
