摘　　要：An approach to improve the image quality by aperture synthesis in generalized phase-shifting interferometry is proposed.The aperture of the holographic system is enlarged by increasing the recording area to receive a more diffusive spectrum by moving a singular CCD.The sub-object wave fronts are combined with the index of their intensities.This method can avoid the negative effect of environmental disturbance and improve the synthesis efficiency by hundreds of times.The optical experiments have shown that it is simple and robust to stitch the complex object wave front accurately and to improve the imaging quality greatly,especially for the recording of large scale objects.
