On axis interferometric detection using a binary joint transform correlator

# metadata.dc.description.abstract[].value
Recently, we proposed an approach to obtain a single on-axis correlation with use of a joint transform correlator. That method required a displaying device with a determinate configuration, however, in this work we introduce a modification to be used with a modulator without a full 2π phase modulation. This variation is based on a binary joint power spectrum and it requires an interferometric process to obtain a single detection peak. We present a setup to carry out the whole process optically and we show experimental results that validate this new approach.
