Use of moire patterns to determine positions extended to three dimensions. Concept requires two moire templates or grids, separated from each other. Template on side closer to observer contains alternating black and transparent areas. Template farther from observer contains alternating black and white areas. Observer determines position of center of perspective, also receiving indication of depth even without stereoscopic view. Used in rangefinding applications in which precision not required. Also used to gauge location of mobile robot in environment hostile to humans.
