1. A system for acquiring images containing spatial and spectral information of an object, the system comprising: an extended depth of field optical system; a filter array comprising an array of six different sub-filters such that each sub-filter allows the passage of light from a different narrow band of wavelengths of either the red, green or blue spectra, respectively, wherein said six sub-filters are arranged such that any group of four immediately adjacent sub-filters comprises at least one red sub-filter, at least one green sub-filter and at least one blue sub-filter, and wherein said filter array is located at an aperture stop of said optical system; a coded mask located at a focal plane of said optical system; and an imager located beyond the focal plane such that images acquired by the imager are defocused.
