Abstract

This paper proposes an all-numerical robust method to compensate for the chromatic aberrations induced by the optical elements in digital color holographic imaging. It combines a zero-padding algorithm and a convolution approach with adjustable magnification, using a single recording of a reference rectangular grid. Experimental results confirm and validate the proposed approach.
