Optical reconstruction of three-dimensional object from digital holograms using phase information calculated by continuous wavelet transform

Abstract

We propose to record digital Fourier hologram of a 3D diffused object and to reconstruct numerically and optically by using phase-only information. This phase-only information is obtained by using 1D-Continuous Wavelet Transform (1DCWT) from the intensity of digital Fourier Hologram. 3D object image is obtained by numerical reconstruction on computer and optical reconstruction by using a phase-modulated liquid crystal spatial light modulator (SLM). Numerical and experimental results are presented. © 2011 SPIE. © 2021 Elsevier B.V., All rights reserved.
