Abstract

A key problem for the digital holography is to improve the resolution of digital holographic system. We present a system for long-range digital holographic imaging with improved resolution using synthetic aperture method. Imaging system is formed by three sub-apertures, and each sub-aperture receiver contains independently telescope lenses and a CCD device. Through every sub-aperture system, a hologram is obtained. Subsequently, we numerically reconstruct the intensity image and get a synthetic image with the resolution improved. The theoretical analysis and simulated experiment show that the method is reasonable and efficient.
