Lenslet-array-based Stokes vector imagery

We propose a novel Stokes vector imagery system that is capable of determining the full Stokes vector of each pixel in an image simultaneously without any movable parts or modulation. The proposed system creates four channels by utilizing a fixed and rugged lenslet array to produce an exact replica of the incident image through each channel. Analysis of the instrument matrix singularities is discussed. Since all Stokes vector images are determined simultaneously, the processing speed of such a system is high, makes it very attractive for several important applications. Furthermore, the proposed system is expected to reduce several errors associated with conventional imaging polarimeters that employ movable parts.
