Abstract

We discuss a number of anomalies that can result in the output of a joint Fourier transform correlator. Some of these are caused by the writing of the joint power spectrum onto a spatial light modulator having a grid structure. Others result from the binary recording of the joint power spectrum. These effects can cause spurious output cross-correlation peaks and can affect the strengths of the desired cross-correlation peaks.
