Abstract

The present invention is a method and a system for obtaining a digital hologram of a three-dimensional (3-D) scene. The method is performed by illuminating the scene (10) with incoherent white-light, recording multiple projections of the 3-D scene, and finally, computer processing of the projections by the performance of a predetermined sequence of mathematical operations. The method and the system of the current invention are characterized in that a microlens array (MLA, 14) is used to create the multiple projections in an image plane (16) which is projected onto the imaging sensor of a camera (20). This allows the obtaining of all of the multiple projections in a single camera shot.
