Abstract

Moiré topography has been utilized as a practical method for three-dimensional measurement in various industrial and medical fields. However, such shortcomings inherent to conventional moiré topography as low resolution and difficulties in computation are indicated. This means that the measuring points are restricted to points on the contours and that identification of convex or convex of the surface shape is impossible using one moiré picture. These problems are expected to be overcome by phase shift method.
