Abstract
The wave field of real objects can be recorded by using digital holography. However, the resolution of common image sensors is too low to reconstruct the captured object field by high-definition CGHs, because both the pixel pitch and the number of pixels are insufficient for optical reconstruction by such high quality CGHs. Therefore, the technique of phase-shifting lensless synthetic-aperture digital holography is used for capturing the object field. The captured field is binary-encoded after the numerical interference and then reconstructed as the amplitude hologram in high resolution.
