In sampling moiré method, a specimen grating pattern on an object is recorded by a digital camera. A moiré fringe pattern appears by sampling the recorded grating pattern with a constant pixel pitch. The phase analysis of the moiré patterns obtained from one grating pattern provides accurate results of displacement values of the grating. Meanwhile, it is very important to keep our life safely by predicting landslides. If the small displacement of land before the landslide is detected, it is possible to put out an alert before the disaster happens. In this paper, a measurement system for small displacement of landslide by sampling moiré method is developed. ©2010 Society for Experimental Mechanics Inc.
