Graphical user interfaces (GUI’s) are a way to operate digital systems without requiring the user to interact with the computer code directly, thus reducing time and complexity for the user. GUI´s use graphical icons that allow direct manipulation of the system without a need to use text-based programming. Furthermore, GUI’s allow for saving of information inside the code itself, hidden from the user. Müller Matrix Imaging (MMI) is an optical measurement process which allows for the characterization of changes to the polarization state of light as it passes through a material. MMI is time- and labor-intensive, requiring a large amount of information to be recorded and processed; a single analyzed image in MMI requires about 10 000 pixels to be sorted as inputs in 16x16 linear systems. Here, we present a prototype of a GUI to be used in MMI experiments, as well as a system designed for MMI, for use in the Window to the Brain (WTTB) project at the University of California Riverside. This first prototype allows for calculation of the polarization state (Stokes vector) of a 534nm solid state laser. Our GUI also permits a rapid calculation of a calibration matrix (i.e. the MM of air), to perform a calibration test before each experiment. We anticipate that this GUI will facilitate the MMI imaging of the WttB material, nanocrystalline Yttria-Stabilized-Zirconia (nc-YSZ), to aid in optical and mechanical characterization studies.
