Abstract

A simple scheme is presented that enables the measurement of phase changes by recording only two phase stepped images per time frame. Such a scheme is useful for the detection of defects or to monitor vibration characteristics in constructions. The differences between the here presented method and the four recordings per time frame method are discussed. Finally some experimental results are shown.
