Guide to the design of broadband full polarization imager based on dispersion-compensation Savart plates

We provide a broadband channeled, modulated full polarization imaging technology based on dispersion-compensation Savart plates in 2020. It has the advantages of being compact, using the snapshot method, and having a bandwidth of 0.132 µm. It is thus invaluable for applications in diverse fields, including remote sensing, biomedicine, and military science. However, there are a lot of angle restrictions in the system. In practice, these angles cannot achieve such high machining precision, and we use the tolerance or compensation method of errors to analyze the influence of the angle deviation. This analysis will help the system achieve better compactness and stability and provide analysis methods for systems that use crystals as its key elements.
