Multiple invariant optical correlators are considered. By multiple invariance, we mean invariance to more than one distortion parameter per axis of the processor. Space variant optical processors using coordinate transformations and a new phase detection scheme are used to realize such correlators. A theoretical analysis and experimental verification are included.
