Paper Abstract

Fresnel or Fraunhofer holograms recorded on CCD arrays can be numerically reconstructed either by the discrete finite Fresnel transform or by solving the diffraction integral using the convolution theorem. Applications in holographic interferometric deformation measurement with effective digital filtering to enhance the interference phase are presented. The detection, location, and size determination in holographic particle analysis can use reconstructed images which are orthogonally oriented with respect to the hologram plane or employ different angular views reconstructed from a single hologram in a tomographic approach.
