Abstract

An experimental study of Talbot array illuminators (TAIs) has been performed. These devices, first proposed and implemented by Lohmann,¹ are binary phase gratings that, when properly illuminated, give rise to periodic, concentrated areas of light with uniform intensities through Fresnel diffraction. This phenomenon is generally referred to (somewhat misleadingly) as Talbot self-imaging.
