If the appropriate phase and/or amplitude profile is placed on a Diffractive Optical Element (DOE) it can practically generate an image of an object (hologram) by diffraction of the light. The problem of generating computer ...

Presentamos un diseño compacto para generar y testear diferentes vórtices ópticos con momento angular orbital (OAM). El diseño consiste en una máscara que contiene un holograma binario y un pinhole. Cuando la máscara es ...

We report a new theoretical and experimental study on hologravures, as holographic computer-generated laser-engravings. A geometric theory of images based on the general principles of light ray behaviour is shown. The ...

A system prototype to write computer-generated holograms on recordable compact disc media (CD-R) by modifying and gaining control over the standard writing procedure of a conventional optical recording drive is presented ...

A new approach to perform image addition via computer generated multiplexed holograms is described. The purpose of this work is to handle flat objects that are to be stored in a hologram. When holograms are reconstructed, ...

This work presents the fabrication of two-dimensional diffraction gratings in diamond-like carbon (DLC) thin films, with applications in computer-generated holography and micro optics. In order to achieve high diffraction ...
