Abstract
Holography stands as a significant technology for achieving three-dimensional (3D) wavefront recording and reproductions with continuous depth sensation. Spatial 3D contents can be recovered from a digital hologram using numerical Fresnel back propagation algorithms. However, the space-bandwidth product (SBP) of a holographic 3D imaging system is technically limited to keep the signal spectra away from the unwanted spectra, thereby resulting in a reduced field of view or resolution of an image. In this paper, we proposed a scheme for high bandwidth holographic 3D imaging that uses Kramers–Kronig Fresnel digital holography system. The Kramers–Kronig relations (KKR) are employed to derive the propagated complex wavefront of 3D object from recorded Fresnel digital hologram, then accurate 3D contents of the target object are reconstructed through numerical back-propagation diffraction algorithm. In contrast to the conventional off-axis Fresnel digital holography techniques, the proposed method can suppress streak-like noise and aliasing caused by limited space-bandwidth utilization and depict high-quality reconstructed 3D images.
