A novel neural network design, in which nonlinearities are created by feedback, is described. It is called the HOFNET. The design is suitable for optical implementation because it is tolerant of the limited dynamic ranges present in optical systems. An optical system with electronic feedback was constructed and its operation is described.

Inspec keywords: feedback; holographic storage; optical information processing; Fourier transform optics; nonlinear systems; neural nets; computerised pattern recognition
