Abstract
A mask for use in compressed sensing of incoming radiation includes a material that modulates an intensity of incoming radiation, a plurality of mask aperture regions, and one or more axes of rotational symmetry with respect to the mask aperture regions. Each mask aperture region includes at least one mask aperture that allows a higher transmission of the incoming radiation relative to other portions of the mask aperture region. The relative transmission sufficient to allow a reconstruction of compressed sensing measurements and has a shape that provides a symmetry under rotation about the one or more axes of rotational symmetry. A mutual coherence of a sensing matrix generated by a rotation of the plurality of mask aperture regions is less than one. An imaging system for compressed sensing of incoming radiation including such a mask is also provided.
