Paper Abstract

We demonstrate in the laboratory the construction and correlation of a matched filter correlator using only a single curved element. Previously we demonstrated a correlator that uses a converging reference beam for constructing a matched filter so that when performing correlation, the correlator does not require a lens for taking the inverse Fourier transform. This paper demonstrates an extension in which we use a diverging beam from a laser diode for constructing the hologram in order to avoid a lens for generating a converging beam. The matched filter is turned upside down and reversed for use in the correlator.
