Paper Abstract

The paper introduces a new method of digital image correlation by making use of the transitioning state of the digital micro-mirror device (DMD). The projector should be given an OFF time in order to introduce flashing light for dynamic imaging. The dark period between DMD’s ON time is used to solve the saturation problem. Multiple captures are made during each projector cycle. The final unsaturated camera image can be obtained by combining all the images captured during that cycle. Experiments conducted demonstrate the success of the proposed method in performing digital image correlation for highly reflective surface.
