Experiments on Pseudoscopic 3D Display Using Moiré Method

Abstract

Moiré appears when two patterns with slightly different pitches are put together. If there is a gap between these two overlapping patterns, the moiré will then have a binocular parallax, which allows the viewer to experience a depth (floating above the surface or sinking). We explain how we, by overlapping moiré and an ordinary two-dimensional image, produced a prototype "pseudoscopic 3D display" in which the moiré had depth before and behind the 2D image. We also quantitatively analyzed the relationships between the moiré pitch and depth reproduction. The analysis results closely matched the results of a subjective evaluation test. Furthermore, to verify the effectiveness of our system, we produced two types of pseudoscopic 3D display (print type and full-color moving image display type) , and verified that a pseudoscopic 3D display with moiré has visually adequate depth.
