Abstract

The resolution of digital holography as an optical imaging system is described by the point spread function of the system. The point spread function of double aperture digital holography is determined. It promises the possibility of a resolution increase by the concept of synthetic apertures. First results of numerically reconstructed wave fields from synthetic digital holograms combined of two single holograms are shown. Furthermore an experimental method for the exact determination of the mutual CCD position and orientation is presented.
