It is a key problem to get the high resolution and large field of view (FOV) of dynamic measurement in the display technique. In this paper, Charge Coupled Device (CCD) was synthesized with seams to be a display unit. A reconstruction method is proposed which combines the principles of synthetic aperture and phase retrieval to detect the 3D particle target with synthetic CCD. In the simulation experiment, the correlation coefficient of surface l is 0.73217 between the reconstructed image and the simulated particles target image. The pictures from the experiment depicts the particle is not only clearly visible at the normal region but also at the seams. The optical information can be recovered well of the high resolution and large field of view (FOV) with this method.
