1. A spectral imaging apparatus for processing electromagnetic (EM) radiation, the EM radiation originating from a target scene and comprising a wide range of frequencies, the apparatus comprising:
a dispersive element for receiving EM radiation from the target scene and promoting differing amounts of dispersion depending on the frequency of the EM radiation; a deformable lens arranged to receive EM radiation from the dispersive element; and an imaging sensor for detecting EM radiation across the wide range of frequencies, and arranged to receive EM radiation from the deformable lens; wherein the deformable lens is operable to adopt any one of a plurality of focal conditions, each focal condition tending to focus a different range of the EM radiation at the imaging sensor, each focal condition thereby defining a component band for the EM radiation. |
