摘要

We present a novel optical configuration that yields a fringe pattern that represents the slope changes of a three-dimensional object with a twofold increase in sensitivity. The method offers controllable sensitivity over a wide range. We accomplish it by modifying the in-plane displacement sensitive configuration of speckle interferometry. The detailed theory and the experimental results are presented with a brief discussion on the limiting aspects of the configuration. (C) 1998 Optical Society of America. [References: 4]
