Abstract

Abstract. Because a Fourier transform relates time (t) and frequency (ν) of an optical signal, we expect and observe interrelationships between systems operating in the t domain and systems operating in the P domain. Indeed, it appears that each t system has a dual ν system that uses an essentially identical setup and measures the same underlying phenomenon. The same duality exists in the other direction as well (there is a t system dual to each ν system). This preliminary study of ν↔ interrelationships shows that many otherwise diverse optical information processors are readily related by the ν ↔ t duality concept.
