Abstract
Although integral holography has many promising advantages in
the field of 3D imaging, the resolution of reconstructed holographic
image is still limited by the insufficient information captured. To
improve the reconstruction quality, an integral Fourier holographic
imaging method based on micro-scanning of the micro-lens array is
proposed in this paper. The micro-scanning of the micro-lens array
can increase the sampling
rate in spatial frequency domain and the information of the generated
Fourier hologram, which will eventually eliminate the overlapping
effect in the reconstructed 3D image. Experiments for different micro-scanning
modes are carried out to verify the feasibility of the proposed method
and to show that the reconstruction quality is effectively enhanced.
