Abstract

We propose an alternative reconstructing strategy in digital color holography, based on the hologram stretching techniques. With a simple adaptive affine transformation on the digital color holograms and a correlation-matching procedure applied on their numerical reconstructions, we are able to manage the digital color reconstructions of the same object in order to obtain their perfect superimposition. We test our procedure in several experimental cases considering holograms recorded in both microscope configuration and lensless configuration. Finally we give a procedure, based on the National Television Systems Committee (NTSC) coefficients, to synthesize a single hologram that contains the information associated to the three colored numerical reconstructions. Numerical analysis and display tests are used to evaluate the effectiveness of the proposed method.
