Abstract
Resolution and speckle size in the reconstructed wavefields of digital holography depend on the aperture defined by the size of the CCD-array. Here we introduce the concept of synthesizing a larger aperture by recording simultaneously the same scene by at least two CCD-arrays. It is shown that an improvement in resolution can be obtained which corresponds to a virtual aperture of the size defined by the distance between the two CCDs. This is shown by a comparison of the point spread functions of systems with one and with two apertures. Open problems are stated and future prospects are presented.
