ABSTRACT:
This invention relates to a coded aperture imaging system wherein a detector array is arranged to receive radiation from a scene via a coded aperture mask. The coded aperture mask provides a plurality of uncorrelated coded aperture arrays at different positions on the mask. Each distinct coded aperture array therefore passes coded information to the detector array. The intensity pattern at the detector array, which is a summation of the intensity patterns from each of the distinct coded aperture arrays, can be decoded separately for each coded aperture array to reconstruct a separate image associated with each coded aperture array. In this way the present invention teaches a coded aperture array means with multiple, simultaneous fields of view. The different fields of view can be different sizes and/or resolutions. Preferably the coded aperture mask is reconfigurable.
