Abstract

Design, construction and evaluation of a prototype to detect red interference Moiré patterns are presented. Fringes are generated by a red solid state laser whose light beam is transmitted through grids constructed ad-hoc with Moiré patterns. These gratings are produced using photochemical techniques and a programming original code. A printed circuit board (PCB) of commercial red photodiodes mounted in a mechanical assembly optical rail ensures experiment reproducibility and allows light intensity quantification in different areas of the selected transmitted pattern.
