Optimización teórica de sistema electromecánico para obtención de fase para un interferómetro de trayectoria común

Abstract

In this work, the mechanical optimization for generating of equally spaced phase shifting steps is proposed for the phase difference extraction between a reference and a probe object in a double aperture common-path interferometer. Design and simulated results are shown for the gears mechanical transmission system proposed to increase the precision and control of a transverse traslation difraction grating; in order to obtain equidistant linear displacements
