Digital optoelectronic processor for fast Fourier transform in binary sign-bit-system

摘要

A novel structure of an optoelectronic multiprocessor digital Fourier-computer which uses Hartley transform and representation of operands in the form of a binary sign-bit numbers is proposed. The dynamic circulator fiber-optic storage device is taken as a random access memory. The use of Hartley transform in the proposed Fourier-computer and representation of operands in the binary sign-bit number system in conjunction with the use of fiber-optic memory devices make it possible to compute coefficients of Fourier-series in practically real time.
