Detecting Cells with the Scatter Plot Pattern of an Orthogonal Scattering Mueller Matrix

We investigate the characteristics of the elements of an orthogonal scattering Mueller matrix for spherical cells. Two parameter scatter plots with x- and y-coordinates determined by s₁₁+s₁₂ and s₁₁?s₁₂ values are drawn. The unexpected patterns of these two parameter scatter plots are more sensitive to the relative refractive index of cells. When a series of scatter plots in a database for cells' light scattering are prepared in advance, an image correlation technique can be used to judge the patterns of scatter plots, which shows a promising approach to reveal the tiny change of cells in a flow cytometry.
