Experimental realization of a fiber-optic-based multichannel digital correlator.
An experimental demonstration of a new realization of a multichannel digital correlator is presented. It uses optical fiber networks based on a tree topology to implement the required passive delay lines and intensity addition followed by electronic thresholding to perform the multiplication function. Application of this device to laser light scattering and spectroscopy in radio astronomy and the potential for operating at higher bandwidths are discussed.
