This paper introduces a system that provides estimations for the 2-D or 3-D position of a point target, with high spatial resolution. The system contains a conventional imaging lens being attached to a special diffractive optical element. The super resolved position estimation to be utilized with pixelated detector arrays is obtained due to the use of this optical element, which replicates the imaged point source on the detector array plane. A relatively simplified computation algorithm applied on the composite image yields the desired position estimation.
