Incoherent-erasure joint-transform correlator

Not Accessible

Your library or personal account may give you access

Abstract

We propose a nonlinear joint-transform correlator that is produced from the erasure of a real-time hologram by the joint-transform spectrum. Our analysis of this incoherent-erasure correlator with a four-wave-mixing readout arrangement indicates that the performance of this correlator exceeds that of the phase-only correlator.
