 note = {application/pdf, 論文(Article), By the 3-D image measurement methods, such as space pattern projection technique and moire topography, to discern the exact striped order is taken as the foundations of measure­ment. Because the depth range of an object is computed by correspondence relation between the fringe order of a realective pattern, and the depth of an object. Multiple images needs by the conventional method. Moreover, by methods, such as the moire method and the interfering method, this is known as the problem of phase unwrapping of moire patterns or interfering patterns. Because of this problem, it is difficult to calculate the absolute phase or to discern the relation between the fringes, especially in the cases in which the fringes are discontinuous or the objects are isolated, and so forth. 
The technique of using modulated projection with 3-D information is presented. A new fringe pattern whose fringe intensity or color changes with its order can produced. The fringe order can be extracted easily from the fringe intensity or color, and the absolute phase or absolute depth range can be obtained solely by its intensity or color.},
