Abstract
In order to measure 3-D surface of objects by using phase- shifting method, based on shadow moire topography, two stages are planned. The stages are moving the grating vertically, which produces a change in moire pattern; rotating the grating, which results in the constant phase-shift regardless of the moire fringe order. The paper emphasis is on describing the novel method, and justifying it by error simulation test. The experimental results show that this technique is available for some industrial fields.
