Abstract

The recording and numerical reconstruction of digital lensless Fourier hologram is analyzed. Based on the quadratic phase mask of the reconstructed image field the two common methods for phase reconstruction are discussed and compared by computer simulations. The results show that the automatic phase compensation approach has stronger toleration for noise than that of the digital holography combined with the digital lateral shearing interferometry approach. But the latter method can avoid the irksome two-dimensional phase unwrapping process. In addition, the standard onedimensional phase unwrapping procedure must be applied before shearing procedure in order to eliminate the phase jump of the original phase map. An effective method to eliminate the linear term of the shearogram automatically have been proposed and demonstrated.
