Abstract

A new type of moiré and its application to topography are discussed. Moiré fringes are generated by observing a grating projected on an object under test with a scanning imaging device. The general equations of the projection-type moiré topography are given. By controlling the phase, the pitch, or the direction of the virtual grating corresponding to the scanning lines of the imaging device, the automatic sign determination of the contour lines is accomplished. By the use of a high precision flying spot scanner with a new type of CRT(DD-tube) and a minicomputer system, an experimental measurement system is developed. Very significant is the fact that a contour line system and a sectional shape of the object are automatically reconstructed and displayed on a color TV monitor.

  15. The difficulty of the analysis largely depends on where and how the coordinate system for describing the configuration of the moiré fringes is set. In many papers on the Meadows and Takasaki method, the coordinate system is defined so that the origin is located on the real grating, and two of the three axes are on the grating plane. In the projection-type moiré topography, however, the definition is not unified; in Ref. 10, the origin of the coordinate system is set in the object, and one of the three coordinate axes coincides with the optical axis of the observation system, whereas in Ref. 11, the situation is discussed where the projection and the observation grating are located on a plane, and the two coordinate axes are defined on the plane.
