Moiré interferometry is increasingly being applied to investigations in experimental mechanics. The present work seeks to address the problem of automated ‘real-time’ analysis of interferometric Moiré fringe patterns to obtain strain values. To this end, a portabe system is constructed to demonstrate the use of an electro-optic heterodyne technique on a single point, single component of strain basis. The prospect of expanding the setup to enable whole-field strain tensor evaluation is also discussed.
