The polarization aberrations of a fold mirror can be compensated by orienting a second fold mirror's p-polarization with the first mirror's s-polarization. This crossed-mirror configuration compensates the polarization for a single angle to zero and leaves a linear variation of diattenuation and retardance for a spherical wavefront. Two sets of crossed fold mirrors when properly oriented compensate the remaining linear variation and leave a much reduced quadratic variation in a large compensated field of view.
