Mueller calculus is a matrix method for manipulating Stokes vectors, which represent the polarization of light. It was developed in 1943 by Hans Mueller. In this technique, the effect of a particular optical element is represented by a Mueller matrix—a 4×4 matrix that is an overlapping generalization of the Jones matrix.

For this reason, many Mueller matrix polarimeters have been proposed, and many technologies are applied to Mueller matrix polarimeter such as proposed based on electro-optic (EO) modulators [2], liquid crystal variable retarders (LCVRs) [3], rotating retarders [4], [5], [6], and snapshot systems [7], [8].
Mueller matrix polarimeters (MMPs) are designed to probe the polarization properties of optical scattering processes. When using a MMP for a detection, discrimination, classification, or identification task, a user considers certain elements of the Mueller matrix. The usual way of performing this task is to measure the full Mueller matrix and discard the unused elements. .We present a new snapshot technique for performing spectrally resolved Mueller matrix polarimetry.

A method for the correction of systematic errors generated by large orientational and retardance errors in the polarization optics in the dual rotating retarder polarimeter is presented. Small orientational and retardance errors (<1°) can lead to large errors in the measured Mueller matrix (> 10% in some matrix elements).We previously developed a Mueller matrix microscope by combining a dual-rotating-retarder device with a commercial microscope, which holds promise for pathologic diagnosis applications.
