Abstract
We present an optoelectronic approach to enhancing the resolution of digital holograms. By combining interference patterns of differently shifted wave fields a high resolution measurement of the object waves complex amplitude is obtained. A spatial light modulator is used to generate the phase only transfer functions of wave field shifts.
