Abstract
A coded mask apparatus is provided for gamma rays. The apparatus uses nested masks, at least one of which rotates relative to the other.
Claims24
A mask apparatus for use in compressed sensing of incoming radiation, comprising:
- one or more nested coded masks, each of the masks having a body being formed from a material that modulates the intensity of the incoming radiation;
- wherein each of the one or more masks has a plurality of mask aperture regions, that that allow a higher transmission of the radiation relative to other portions of the one or more coded masks, the higher transmission being sufficient to allow reconstruction of compressed sensing measurements.
