Normalization in computational optics

Applied Optics
The use of computational techniques to understand the behavior of physical phenomena is well established. Nonetheless, numerical noise is still one of the most common barriers hindering the use of mathematical models to their full potential. A frequent source of issues is the mixing of scales in a given model.

Optical and Optoelectronic Computing

1989
Publisher Summary This chapter presents the fundamentals of optical computing and discusses the elements of optical computers—such as memories, logic arrays, and input/output devices. The different types of optical processors are also discussed. The basic mathematical operations for optical computing include addition, subtraction, and multiplication.

Optical expanders with applications in optical computing

Applied Optics, 1993
An optical system called the optical expander is described and investigated. The optical expander electro-optically expands an optical Boolean pattern encoded in d bits into an optical pattern of size N bits. It is assumed that d is equal to c log(2)N for some constant c, and each expanded pattern is orthogonal to the others.

Developing diffractive optics for optical computing

IEEE Micro, 1994
Diffractive optical elements easily handle tasks such as the generation of uniform arrays of beams, beam steering and focusing, and aberration correction that conventional optics alone often find difficult or impossible. Here we review the design, fabrication, and performance of DOEs for use as free-space interconnection elements in optical-computing ...

Perspectives in optical computing

Computer, 1998
30 years ago, the author was certain that electronics was reaching its natural limits and that optics alone could offer massive parallelism. In this article, he explains how he had it all wrong and how-after enduring a time of fear and doubt-he developed new confidence about the future of optics.
