White light-in-flight holography

Abstract

A two-step approach to white-light holography is presented where the first step produces a light-in-flight hologram. The second step is classical recording of the real pseudoscopic image across a new holographic plate. Reconstruction is provided in white light. As a final result, a color coded presentation is obtained with a rainbow appearance encoding the actual contouring of the object. A theoretical analysis is given in detail, and experimental evidence of expectations is demonstrated on different subjects.
