Digital recording and reconstruction of holograms in hologram interferometry and shearography

Applied Optics, 1994
The fundamentals of digital recording and mathematical reconstruction of Fresnel holograms are described. The object is recorded in two different states, and the holograms are stored electronically with a charge-coupled-device detector. In the process of reconstruction the digitally sampled holograms are applied to the different coherent optical ...

Computational Reconstruction of Images from Holograms

Applied Optics, 2002
The equations to reconstruct an image plane from a hologram are developed. This development is carried out for planes parallel to the hologram, which allows fast computation through the use of fast Fourier transforms. Algorithms for a digital computer are developed so images can be reconstructed, both with and without the Fresnel approximation, from a ...

Reflection hologram for reconstructing deep images

Optics Letters, 1997
A method to record deep and blurless images as a reflection hologram is proposed. A slit was used in the recording process in the same manner as for a rainbow hologram. The reconstructed image was monocolor and could be observed from wide longitudinal angles when it was illuminated by an extended white-light source such as a fluorescent lamp.
