This high level monograph for the optics research market explores a large number of novel
interactive methods and algorithms for calculating the transmission function of phase …

Separable binary-phase array illuminators for fan-out up to 1024× 1024 and~ 65% two-
dimensional efficiency are designed by simulated annealing with constraints for maximizing …

A review and comparison of design procedures for binary-phase and multiphase Fourier
gratings used as array generators is presented. Grating structures include one-and two …

The authors discuss digital optics, a technology for processing, transport, and storage of
optical digital information. Digital optics offers both the high temporal bandwidth of fiber …

Publisher Summary This chapter reviews the progress made in the area of digital free-space
optics. Digital computing is a complex task. The chapter discusses all three areas of …

Dammann gratings are binary-phase Fourier holograms that are used to generate an array
of point sources. Using symmetry and separability arguments, we extend Dammann's …

The modified-signed-digit (MSD) number system offers parallel addition and subtraction of
any two numbers, with carry propagation constrained only between two adjacent digits …

Carry-free addition and borrow-free subtraction of modified signed-digit trinary numbers with
optical symbolic substitution are presented. The proposed two-step and three-step …

This paper introduces programmable arrays of optically inter-connected electronic
processors and compares them with conventional symbolic substitution (SS) systems. The …

We propose a simple recoded trinary signed-digit number representation for parallel optical
computing. This technique performs multidigit carry-free addition and borrow-free …
