    We propose a new nonoverlapping synthetic aperture digital holography without additional instruments. The relative distance between adjacent subholograms is estimated from the cross-correlation of reconstruction images from each subhologram. From the cross-correlation, the shift amount of the reconstruction object is estimated. Then, the relationship between the position of the subhologram and the reconstruction object from it enables the relative distance between adjacent subholograms to be calculated. The nonoverlapping synthetic aperture experiments with two subholograms are presented in two ways by changing the object. In the experiments, we show that the resolution of the reconstruction object increased twofold, thanks to the nonoverlapping.
