Comparative Analysis of Techniques to Pick-up Hologram Data from Real Object

Abstract

Holography is one method to record the information from a real scene, but it requires coherent illumination and the lack of resolution of the pick-up device may strongly limit the size of the object recorded. It is also possible to generate a hologram of a real scene in incoherent illumination condition by using techniques likes integral imaging or multiple imaging, but the spatial resolution provided from these methods is usually quite poor. Hologram can be made from a virtual scene with a computer, but the heavy computational load limit the size of the scene, and it is difficult to create precise models of complicated objects. In this paper, we analyze the different techniques used to pick-up 3D data from a real object such as holography or integral imaging. And then, we present the first result of a simulator which is developed to evaluate the key parameters of hologram data according to the pick-up system. Preliminary results may be possible to evaluate their performance and to choose the optimal method one should use according to the resolution, the depth of field or the angle of view.
