Abstract

We show that a finite Talbot array illuminator (TAI) with reconstruction field at a fraction of the Talbot distance (z equals MZ_T/N), can be interpreted as an array of M (or 2M) interlaced pixelated lenses sharing a common focal length f equals MZ_T/N. We found also that the transmittance of a finite TAI can be expressed as a single pixelated lens modulated by a phase grating whose basic cell has M (or 2M) pixels. Based on this description of a TAI we propose a method to improve its performance as generator of a finite spot array at the reconstruction plane.
