Automatic experimental optimization of capture of interference patterns of a Double-Aperture Common-path interferometer to reduce negative effects of mechanical vibrations

Abstract

This paper reports an experimental system implemented to a Double Aperture Common Path Interferometer (DACPI) which automatically captures interferograms at the moment in which the system presents a minimum of mechanical vibrations. This is determined by m x n matrix analysis of a region of interest of the interferogram in question seeking to capture more stable images which will have an impact on an improvement for their subsequent analysis when the system does not have an optimum mechanical isolation. Experimental and comparative results with a non-optimized system are presented.
