A coded aperture sensing system includes a tunable coding aperture positioned relative to one or more electromagnetic (EM) detectors and voxels to scatter EM radiation traveling from the voxels towards the EM detectors. The system also includes a controller configured to determine EM fields at each of the voxels. A method includes determining a desired aggregate coding matrix of the tunable coding aperture, determining control parameters corresponding to the desired aggregate coding matrix, applying sequentially each of the control parameters to tunable inputs of the tunable coding aperture, and determining the EM fields at each of the voxels. Determining the EM fields includes determining the EM fields at least in part as a function of EM fields detected at the EM detectors responsive to each of the controls being applied to the tunable inputs of the tunable coding aperture.
