This invention relates to coded aperture imaging apparatus and methods. In one aspect a coded aperture imager has at least one detector array and a reconfigurable coded aperture mask means. A reconfigurable coded aperture mask means can display various coded aperture masks to provide imaging across different fields of view and/or with different resolution without requiring any moving parts or bulky optical components. More than one detector array can be used to provide large area imaging without requiring seamless tiling and this represents another aspect of the invention. The present invention also relates to the use of coded aperture imaging in the visible, ultraviolet or infrared wavebands. The use of coded aperture imaging for imaging through a curved optical element is taught as the image decoding can automatically remove any aberrations introduced by the curved element.
A coded aperture imaging system configured to operate in the ultra violet, visible or infrared wavelength interval and comprising a detector array and a coded aperture mask, the coded aperture mask is electrically reconfigurable to produce coded aperture arrays providing one of:
A coded aperture imaging system comprising a detector array and a coded aperture mask which is reconfigurable, and the reconfigurable coded aperture mask incorporates a controller adapted to cause at least one coded aperture mask to provide a coded aperture array.
A method of imaging comprising the steps of:
A method of coded aperture imaging in the ultra violet, visible or infrared wavelength interval and comprising the steps of:
