ABSTRACT:
An imaging system (10) contains a diffractive optic lens (14) which allows for a relatively accurate representation of objects within a field of view. These objects are associated with light rays (20, 22 and 24) which are made to impinge upon the diffractive optic lens (14) and thereafter are made to be received by an imaging surface (12) at a receiving angle which may be determined by the structure of the diffractive optic lens (14). The diffractive optic lens (14) may be placed within the typical dewar (16) of the image acquisition system (10), may be removable deployed over the imaging surface (12), or alternatively, the diffractive optic lens may be etched upon the front side of the imaging surface (12) by the use of standard etching techniques such as lithography, diamond turning and the like.
