Abstract

This work discusses coded aperture functioning in the visible spectral range. A MURA coded aperture was implemented using laser ablation by evaporation of titanium film from a transparent substrate. The optimal laser parameters to make a high-contrast aperture are shown. The paper also present an algorithm based on periodic correlation which has been developed for image reconstruction. Experiments were carried out with the aperture of rank 37 with a minimal element of 130 μm. The images obtained during the experiment demonstrate the effectiveness of the proposed aperture implementation method and the developed image processing algorithm.
