Abstract

This paper describes a residue processor which converts residue numbers represented by phase-shifted lightwaves into decimal numbers with positional notation. This is achieved by using a photodiode array for detecting the highest intensity maximum in an interference pattern. Expansion of the setup by an input stage in the form of binary-driven modulators and by a discriminating binary output stage yields a device which can add two or more numbers with extreme speed, at the same time ensuring compatibility with traditional electronic computers.
