    Optical Computing. Systems Sobha Gottipati Prathima Rao Anjali Panicker. Introduction "Optical Computing" means the use of light as a primary means for carrying out numerical calculations, reasoning, artificial intelligence, etc.. The field of optical computing is quite broad. Applied Sciences, an international, peer-reviewed Open Access journal. Computer-generated holographic techniques offer an efficient way for reconstructing holograms without complicated interference recording systems. In this work, we present a technique for generating 3D computer-generated holograms (CGHs) with scalable samplings, by using.   As far as classical optics go, this is one must have book. It is divided in three parts: I Geometrical Optics (pp. ), II Wave Optics (pp. ) and III Quantum Optics (pp). If you prefer a more modern approach, I second the above poster's suggestions for "The Light Fantastic" and the surprisingly compact introduction by Fowles.

Computer-generated holography (CGH) is the method of digitally generating holographic interference patterns.A holographic image can be generated e.g. by digitally computing a holographic interference pattern and printing it onto a mask or film for subsequent illumination by suitable coherent light source.

Holographic optics: optically and computer generated. [Ivan Cindrich; S H Lee; Society of Photo-optical Instrumentation Engineers.; New. Digital holography optically generates a hologram, which is then recorded on a CCD camera, and an image is reconstructed using digital techniques.

This chapter discusses the converse, i.e., the hologram is digitally generated and the reconstruction is performed optically, a process known as computer-generated holography (CGH).Cited by: 1. We define computer-generated volume holograms (CGVHs) as arbitrary 3D refractive index modulations designed to perform optical functions based on diffraction, scattering, and interference phenomena.

CGVHs can differ dramatically from classical volume holograms in terms of coding possibilities, and from thin computer-generated holograms in terms of efficiency and selectivity.

SPIEComputer and Optically Generated Holographic Optics; 4th in a Series, pg 2 (1 December ); doi: / Read Abstract + The use of computer aided design (CAD) techniques in micro-optics is suggested in an effort to make the development of optics similar to the development of integrated VLSI electronics.

Computer-generated holograms (CGH’s) are diffractive-optical elements that offer the possibility of creating wave-optical display systems that are under complete computer control. Because CGH’s can control all aspects of the optical wave, three-dimensional imagery can be presented to an by: The use of computer generated holograms for the testing of aspheric wavefronts is described.

An analysis of the errors produced by emulsion movement, incorrect hologram size and position, and distortion in hologram plotter and photoreduction lens is given, and it is shown that all the errors are proportional to the slope of the aspheric wavefront.

We propose a new iterative algorithm for obtaining optimal holograms targeted to the generation of arbitrary three dimensional structures of optical traps. The algorithm basic idea and performance are discussed in conjunction to other available algorithms. We show that all algorithms lead to a phase distribution maximizing a specific performance quantifier, expressed as a function of the trap.

At infrared and visible wavelengths, the value of synthetically generated holographic optical components is well established (61). This is mainly because your computer screen is several inches away from your eyes, while a book is usually much closer.

Add to that the blue light emitted by the computer screen and you have two environments that are quite different and using the glasses in ways they weren’t meant to be used can lead to eye strain.
